When in editor (i try to better spread alien races) i try to rename a Red Star i read in left box dimension 160.9 the exception rise: "size 1609 not from minimum and maximum"
Map generated in 1.0.4 engine
(Place new rnd system features is still "out" [:(] )
I hope this will help you ;)
P.S. The game will not crash... but i don't know if will be after some time...
