possible bug causing players to get kicked

Could StackModifier be the cause?

Player was disconnected! (Kicked: RPC Error in DoPlace)

Planner.DoPlacement

That method is called from Rust’s DoPlace RPC. If the replacement throws an exception, Rust automatically disconnects the player with:

Kicked: RPC Error in DoPlace

 

In StackModifier.cs, lines 2530–2598:

[AutoPatch] [HarmonyPatch(typeof(Planner), nameof(Planner.DoPlacement))] internal class Planner_DoPlacement_Patch

The prefix then replaces the original method entirely:

static bool Prefix( Planner __instance, Construction.Target placement, Construction component, ref GameObject __result)

Because it always finishes with:

return false;

Client sends DoPlace RPC
↓
Planner.DoPlace processes it
↓
Planner.DoPlacement is called
↓
StackModifier Harmony prefix executes
↓
Unhandled exception
↓
Rust reports "RPC Error in DoPlace"
↓
Player is kicked

Normal Oxide hook exceptions are generally caught and logged as Failed to call hook. A Harmony prefix running inside the RPC is much more likely to escape into Rust’s RPC error handling.

That can actually be triggered by any plugin because I harmony patch the vanilla method in general.

The only problem is I have no way to track down the plugin causing it.

I suggest looking at any plugin that messes with building in general like Bgrade plugins auto-upgrade, object stacking, etc 


I do not have any problems building with my Bgrade plugin or with vanilla.
