I'm running the Jan 15 Mac OSX debug build.
For some reason at times the game loses the position of a squaddie and thinks he is one off of where he should be. I'll keep watching and see if I can determine what causes this. It's annoying to have a squaddie walk into a wall and then get stuck.
I don't know if my second issue is a bug. I've done two of the capture landed ship missions and nothing ever came of them. The only reason that I can see is my base that had the large and small alien hangers was not the base the capturing troops call home.
