So, I made a map with custom csg, metal and landing zones. Saved, started AI skirmish, everything is fine. I went back to editor to make some minor changes, and got a map with no customizations. I started another skirmish - details are in place. I opened editor, pressed preview all, all the details are in place. I zoom in into the planet, it reloads and everything is gone! Below are the pictures The same or worse thing happened to my other map. I've spent 1,5 hours making cool terrain, when I loaded it in game, half of custom csgs was missing. But metal placed on those pathable csgs was there, just hovering in the air. I could placed those csgs again, but worst part is, you can't delete metal hovering in the air.
