Additional Notes

Using Verse. It may be caused by too much data loading on join, leading to a crash. Not sure why it happens after ~30 minutes—possibly data accumulation from other players. Strange because if 4 players join at the same time, everything works. But delayed joins fail. This is a critical issue.
