Why are you blaming starforge for this crashing accident? If you know what things crash the game don't do it. Many people use starforge just fine without having their game crash.
Come here and see if those are the reason why your map crashed. If it does not solve anything post your map. Yes, don't use Starforge for Isometric terrain it is not that good. Use another editor if you want to use isometric terrain.
