HostOwner

The hosting player takes ownership of chosen objects that lie in its active area: stations, bosses, or any list of prefabs and components. Their logic then runs on the host, and so do the host's mods for them.

hostowner status: how many objects the host owns and took over

Why: every networked object is simulated by one client, its owner. Since Valheim 1.0 the server hands ownership out, and whoever reached an object first keeps it while they stay near. A smelter that a player without a speed mod got to first runs at vanilla speed; a boss that one player fights alone is invisible to a damage meter on another. With this mod the host takes such objects over within two seconds while it is in range, and vanilla gives them back the usual way when the host walks off.

• Stations (on): everything with a Smelter, CookingStation, Beehive, SapCollector or Fermenter component, mods included.
• Bosses (off): every creature flagged as a boss.
• Components, Prefabs: your own lists.
• An object a player's client claims back right after the host took it (a taunt mod, a cart) is left alone for YieldSeconds, so mods that claim monsters on purpose keep working.

Console: hostowner status | list | now. Config in BepInEx/config/j1ga.hostowner.cfg; changes apply without a restart.

Host only: inert on clients and on a dedicated server (no player, no active area). No Harmony patches. A small reflection API (HostOwner.HostOwnerApi) lets other mods add kinds without referencing this assembly.

Compatibility

Tested with Valheim 1.0.16 (network version 40), BepInEx 5.4.23.5 (BepInExPack_Valheim 5.4.2351).

Who needs it

Who	What
Hosting player (game started with "Start server")	installs the mod — objects of the chosen kinds in its area move to it
Dedicated server	does not work: a server has no player and no active area, the mod stays inert
Other players	not needed; with the mod or without, everything works as usual

Known conflicts

• Mods that manage object ownership themselves will argue with the host. Mods that claim an object once (a taunt, a cart) get along: the host yields for YieldSeconds.
