1.1.12

• Exclude diagonal-only batch contacts by default, including thick slabs sharing a vertical corner edge.
• Add [Batch Replacement] IncludeDiagonalConnections (default false) to opt into corner contacts.
• Retain side connections and linear beam endpoints. Snap envelopes are compared in piece-local coordinates.
• 19 stand-in checks passed; game-reference build has 0 warnings/errors. In-game verification pending.

1.1.11

• Allow connected batches for beams and other compatible non-planar pieces, using shared snap points. Planar groups retain their plane/edge restrictions; batches still select one source prefab.
• MaxPieces remains 250 by default; 0 disables the configurable performance guard.
• Revalidate on click and show all removal/station blockers with local red outlines for four seconds. No piece materials or network state are changed by these markers.
• Release build passed with 0 warnings/errors. In-game connectivity and visual validation pending.

1.1.10

• Batch material checks use the patched Hammer requirement path with full batch quantities, allowing AzuCraftyBoxes container supplies and restrictions to participate.
• The batch HUD distinguishes container-backed availability from inventory counts.
• Surface recognition uses planar snap geometry, reads canonical prefab geometry, and accepts thick slabs with a 1:2 thickness ratio.
• Verification: 13 stand-in regression checks and game-reference Release build, 0 warnings/errors. Live game validation remains pending.

Changelog

1.1.9

• Reduced the single-replacement transaction lock from roughly 1.0 s of fixed safety windows to roughly 0.2 s.
• Placement stabilization is now 0.10 s instead of 0.50 s.
• Support-isolation and post-removal verification are now 0.05 s each instead of 0.25 s.
• All spawn, support, removal and rollback checks remain enabled; only the deliberately conservative waiting windows were shortened.
• This makes rapid beam-by-beam replacement responsive again now that v1.1.8 fixed the actual pivot/snap alignment cause of the missing vertical replacements.

1.1.8

• Fixed replacement positioning for equivalent prefabs that use different local root pivots.
• Single replacement previews are now aligned by structural snap-point centroid instead of blindly copying the old prefab root position.
• Fixes rotated/vertical beam replacements where the new piece could be successfully spawned at an offset, causing the old beam to be removed while the replacement appeared to be missing.
• Applied the same pivot-aware alignment to connected batch replacements.
• Added debug diagnostics that report the applied pivot correction in metres.

1.1.7

• Added a 0.5 s replacement stabilization window before the original piece may be removed.
• Added a support-isolation preflight: the original piece colliders are temporarily disabled and the replacement must survive before the original is deleted.
• Forces WearNTear.UpdateSupport through reflection during the isolation/post-removal checks.
• Added a post-removal survival check and clearer failure logging for multiplayer/network races.
• Specifically hardens vertical beam/pole replacement against the case where the old piece disappeared but the new piece did not persist.

1.1.6

• Fixed a critical replace-only safety issue where holding the replacement modifier could fall back to normal Valheim placement when no compatible target was resolved.
• Improved targeting for thin beams/supports mounted directly on walls by searching compatible overlapping hits near the frontmost aimed piece.
• Updated Valheim 1.0 usage-tag access from Piece.m_usageTags to Piece.m_usage with a legacy fallback.
• Added post-removal verification and rollback so a failed removal cannot permanently leave the new and old piece occupying the same slot.

1.1.5

• Replaced deprecated UnityEngine.Object.FindObjectsOfType<Piece>() calls with FindObjectsByType<Piece>(FindObjectsSortMode.None).
• Removes the two Unity CS0618 build warnings from placement verification.
• Uses unsorted object lookup because PieceReplacer does not rely on InstanceID ordering, avoiding unnecessary sorting overhead.
• No gameplay or compatibility behavior changed from 1.1.4.

1.1.4

• Made single-piece replacement commit safe: the original piece is no longer removed merely because TryPlacePiece returned success.
• Added post-placement verification of the requested replacement prefab, captured position and rotation before the original piece is removed.
• Verification ignores the placement ghost and any matching instance that already existed before the placement attempt.
• Verification retries for several frames and requires the new piece to survive an additional frame before removal of the original target.
• If placement cannot be verified, the original piece remains intact and the BepInEx log records the failed verification.
• Added detailed debug logging for target/replacement prefab, captured transform, vanilla placement result and verified spawned instance.
• Regression target: horizontal 2 m Wood Beam -> horizontal 2 m Ashwood Beam.

1.1.3

• Fixed Valheim 1.0 build references for the connected-surface HUD.
• Added assembly_guiutils.dll, which now contains Valheim's Localization implementation.
• Added UnityEngine.TextRenderingModule.dll, required by IMGUI TextAnchor.
• No gameplay or compatibility behavior changed from 1.1.2.

1.1.2

• Audited Vanilla direct-equivalent build-piece families for the same snap/pivot false-negative seen on beams and half walls.
• Added explicit compatibility for Thatch <-> Darkwood roof panels, inner corners, outer corners and ridges at 26°, 45° and 67°.
• Added explicit compatibility for Wood/Ashwood/Scalewood triangular roof-wall pieces at 26°, 45° and 67°, with inverted variants kept separate.
• Added explicit compatibility for Wood/Ashwood/Timber roof crosses at 26°, 45° and 67°.
• Added guaranteed Wood <-> Ashwood floor 1x1/2x2 and standard stair compatibility independent of user config.
• Added Ashwood alternate angled-beam prefabs and decorated Timber beam/pole variants to their matching structural groups.
• Kept all angle, size, corner type and inverted/non-inverted families isolated to prevent unsafe cross-shape replacements.

1.1.1

• Fixed half-wall replacement between Vanilla material families.
• Added explicit compatibility groups for full 2x2, half 1x2 and quarter 1x1 straight walls.
• Kept wall sizes strictly separated to prevent invalid cross-size replacements.

1.1.0

• Added connected planar-surface replacement with Left Alt + Left Shift.
• Added connected floor/wall detection using plane alignment and shared snap-point edges.
• Added total batch material calculation and inventory availability checks.
• Added bottom-screen batch HUD with piece count, total costs and missing materials.
• Batch replacement is blocked unless the complete material cost is available before starting.
• Added per-piece removal permission and crafting-station validation before a batch commit.
• Added configurable maximum batch size, connection tolerance, plane tolerance and HUD toggle.
• Batch rotation uses the visible seed preview as a delta applied to the complete surface.

1.0.1

• Added explicit safe compatibility for horizontal, 26°, 45°, 67° and vertical Vanilla beam/pole families.

1.0.0

• Initial public release.
