"Westwood hosed up as usual and such units get stuck twiddling their thumbs and only fire back when attacked. What would be the best solution for them?"
I think that "Force hunt mission" would fit it, AI could have a chance to continue attacking the enemy with those released MC units.



DCoder this is a video with the "AI undeploy mindcontrolled deployed units do undeploy anim multiple times" glitch, tested with the r1083 (HD quality available if you don't see the units):

http://www.youtube.com/watch?v=QkQyNzgJqMU

Another strange case: At the beginning and at the end of the video you can see too an odd "Tank vehicle that undeploys into vehicle" animation..

If it helps this is the code I used for the 2 units of the video that are affected:
