Very annoying!
Ok, so I'm in Pattern_Buffer and I finally figure out how to blockade the Yard gate properly so the corrupt Darwinians won't get away (i.e. the right places to put the armor). I get it all set up, and then for insurance against crashing, I leave and come back. And what do I find? all my armor are in different places, all much closer to the gate! Now when the corrupt darwinians come through they'll be able to get a foothold (by taking over battle cannons)! I don't want this at all! Now I'm going to have to destroy all the cannons and start again! What on earth happened?!?
