A player's BuildCraft quarry, which is set over a large area of open water, seems to have either directly or indirectly triggered an Exception while updating neighbours server crash this morning. Not sure what can/ should be done to fix this or prevent it form happening again. Teleported to the coordinates of where the issue occurred and everything seems to be working since the server automatically restarted following the crash.
