I think the issue was in Backpacks, so I've released a new version which should prevent it. Please let me know if the issuse continues after the update.

Same here. Our server crashed today for the first time with the ProcessPlayerBatch error below. After restarting, we also received repeated OnEntitySaved errors.

Backpacks: 3.17.10
ItemRetriever: 0.7.8

Players reported using backpack auto-collection and accessing their backpacks around the time of the crash. Could this be related?

Both stack traces are included below:
