Lethal Elements Theta (v81 rebuild)

⚠️ Unofficial rebuild for Lethal Company v81, maintained by Cpt.Dristyler. Not affiliated with or endorsed by the original authors. Install this instead of the original, not alongside it. Licensed CC BY-NC 4.0 (see LICENSE).

Adds five weather effects to Lethal Company: Heatwave, Solar Flare, Snowfall, Blizzard, Toxic Smog — each with its own hazards (heat exhaustion, walkie distortion, snow accumulation/frostbite, toxic poisoning).

This rebuild (1.3.7) — by Cpt.Dristyler

• Fixed HeatstrokeAudioPatch crashing the whole plugin on v81. The transpiler's CodeMatcher pattern no longer matched the updated game IL and the unguarded Advance/CreateLabel threw, aborting Awake() and silently disabling every weather. The transpiler is now fail-safe (skips only the minor heatstroke audio-muffle if the pattern is missing; all weathers keep working).
• Fixed SnowHindranceTranspiler producing invalid IL on v81. It hardcoded local index 8 in PlayerControllerB.Update; v81 renumbered locals, so the injected div was rejected (InvalidProgramException), crashing init and spamming the log every launch — which also broke other mods patching Update. It now reuses the operand of the matched stloc.s instead of a hardcoded index.
• Resolved a GetRandomNavMeshPositionInBoxPredictable overload ambiguity (v81 added a second overload).
• Rebuilt against LethalCompany.GameLibs.Steam 81.0.5; dependency manifest corrected to mrov-WeatherRegistry-0.8.8 + mrov-MrovLib-0.4.3 (the versions it is compiled against). GUID voxx.LethalElementsPlugin unchanged — configs and the asset bundle stay compatible.

1.3.7 — v81 rebuild by Cpt.Dristyler

Continues from pacoito's last public LethalElementsTheta 1.3.5. GUID voxx.LethalElementsPlugin unchanged — existing configs and the asset bundle stay compatible. Licensed CC BY-NC 4.0.

• Fixed HeatstrokeAudioPatch crashing the whole plugin on v81. The CodeMatcher pattern for SoundManager.SetAudioFilters stopped matching the updated game IL; the unguarded Advance/CreateLabel threw inside the transpiler, aborting Awake() and silently disabling every weather with log spam. The transpiler is now fail-safe: if the pattern is not found it logs a warning and leaves SetAudioFilters unmodified, so all weathers keep working (only the minor heatstroke audio-muffle is skipped).
• Fixed SnowHindranceTranspiler producing invalid IL on v81. It hardcoded local index 8 (ldloc.s 8 / stloc.s 8) in PlayerControllerB.Update; v81 renumbered the method's locals, so the injected div was rejected (InvalidProgramException: Invalid IL code ... div). This crashed plugin init and MonoDetour retried endlessly, dumping the full CIL listing to the log every launch — which also broke every other mod patching PlayerControllerB.Update. The transpiler now reuses the operand of the matched stloc.s instead of a hardcoded index.
• Resolved a GetRandomNavMeshPositionInBoxPredictable overload ambiguity (v81 added a second overload) by pinning the original via the verticalScale parameter.
• Rebuilt against LethalCompany.GameLibs.Steam 81.0.5 (was 73.0.0). Dependency manifest corrected to mrov-WeatherRegistry-0.8.8 + mrov-MrovLib-0.4.3 — the versions the plugin is actually compiled against (the upstream manifest pinned the older WeatherRegistry 0.7.5, which made the mod manager downgrade WeatherRegistry profile-wide and break every weather mod's networking).
