Teleporting units off map

I keep having units being teleported off the map during skirmish matches verses AI

Happened to me last night.

Just happened to me. I had two Condors teleported off the map. Couldn’t get them back within the boundaries, and couldn’t have them die. Tried to win the skirmish with only 40 population, only to have it happen AGAIN! Then I only had 6 population; I don’t care how good you are, you can’t destroy a fully defended base with only 2 marines. Was forced to restart.
