This is the crash report:
crash-2024-05-18_22.54.06-server.txt

Looks like the crash is related to the GSit plugin, server crashed once while getting out of a boat with GSit players on my head. Looks like trying to record multiple players doing one thing together causes the error.

Please provide the full server log, which includes that error message.

Turns out not to be a CoreProtect issue, but with coreprotect throwing errors after a ticking world crash. Sorry for the misunderstanding. Closing this issue now as it is unrelated to coreprotect!
