Important note: Experimentals are sometimes prone to crashing (though we’re getting better and better at preventing them).
We’re actually hot on the trail of the world gen crash, hopefully we’ll at least have an idea of what’s causing it sometime soon.
As for the random crash, said crashes are notoriously difficult to diagnose and fix since without any sort of reliable replication method it’s difficult to determine what the problem was. A reproducible save might help, but without that there isn’t much we can do.
Edit: Dang you Kevin, beating me to the post!
