i logged onto the server i play on after playing on sp and i was almost constantly getting the error (we where under attack) so here is a new set of logs. also cannon shots and missiles froze in mid air after and during the error.

I was able to reproduce it using the process above on a new world, this time with missiles and cannons/cannon/explosive effect. I am uploading the world and logs, one of the ships i was able to reproduce it with is in sector 50, 500, 500, the turrets are cannon turrets.
