Just a heads-up:

This error occurs on the Rust Staging server

Failed to compile: 'LootableCorpse' does not contain a definition for 'SetFlag' and no accessible extension method 'SetFlag' accepting a first argument of type 'LootableCorpse' could be found (are you missing a using directive or an assembly reference?) | Line: 203, Pos: 20

Just wanted to let you know in case you haven't seen it yet.

Another confirmation from me that this plugin is broken since September 2026 force-wipe:

Newest version (4.1.4) fixed it.
