I'm seeing this error in console, but for the life of me, I can't see that it's actually causing an issue - so maybe just an FYI?

[Backpacks] Unable to serialize associated entity of type HeadEntity.​

Thanks, I'll look into it. Probably related to latest Rust update.

Merged post

This has been fixed in v3.13.2. The impact of the issue was that any head bag acquired via the new DLC knife (when harvesting a corpse), if stored in the backpack for some time, when the plugin recreated the item from data storage, the head bag was generic, no longer remembering the source entity prefab, player steam id, player name, clothing.
