I know this would take a lot of effort and coordination, but wouldnt it be possible to set up a short term 3rd server with a group of players who are willing to help with producing the bug, then force a crash on that to avoid revealing any nessecary information?
Another possibility would be to run a backup then force all players to spawn then force the crash and reboot the server to the backup so people end up where they were before the backup
Idk how plausible either of those would be but theyre still ideas.
