Having an issue with Lootr causing lag and eventually crashing the server via watchdog. It has so far only occurred with underwater chests.
I believe the actual issue has something to do with an item because a chest that one player has already opened can be opened by another player and then cause the lag/crash. I've read #100 and #152 and believe my issue may be similar, but I can't read the log well enough to be able to tell. I do not have Terralith but I have quite a few mods that generate structures, so maybe one of them is the culprit?
Hoping this isn't a duplicate but if it is then I apologize!

Also curious about this issue posted on a FTB project where a dev says that the issue is fixed in the upcoming update to Lootr, but this was posted five days after the latest release for 1.19.2. Is there a new version somewhere that fixes this?
Here's the crash log, latest, and debug.

Issue is vanilla Minecraft. For anyone else finding this, the fix is to use a datapack that replaces buried treasure maps.

I'd also suggest checking out Async Locater as another solution to this bug.
