I'm also having this issue using the mod in minecraft 1.17.1 and flan-1.17-1.5.3.jar

crash-2021-07-12_00.38.30-server.txt

It also happens when placing blocks

I've found that all of these actions cause the crash (Will add more to the list as I find them):

• Interacting with any entity inside of a claim
• Right clicking on a block with a stick in a claim
• Placing blocks
