ATM that's all about it. I'm trying to find out what's causing that and if that crashes the client as well, but no crash reports were reported to me, or if this is the cause of some lag.

commented

This shouldn't affect clients. I guess server performance could be degraded if that happened every tick.

Anyway, this is part of height map code (triggered by update of one of those), but I'm not really sure how this can happen (probably some concurrency issue).

How often does it happen? Can you reliably reproduce it after server restart?

EDIT: Found root cause: it's triggered by MineMe owner change + height map update. Anyway, harmless, just annoying.
