Any time I log in it immediately crashes the Ironman server. Have been stuck in this state since 4/15.
I'm was exploring in DIM64 (Ross128b) at the time the server ran out of disk space, and the chunks that loaded around me were not properly generated (lots of odd looking things).
My suggestion is to reset DIM64. The only other person who has been to this dimension is on my team and there is nothing on the ground that would need to be restored if the dimension were reset.
