One that I wanted to point out:
THis seems to be an overall issue, which is with the AI, how pretty much any kind of unit will occaisionally do really weird crap like bounce back and forth between two tiles, or go in circles, or wander past enemies in a random direction without attacking, or strange things like that. On very rare occaisions I'll get one that simply stands perfectly still for a number of turns and doesnt do anything.
Aside from some remaining UI things, this is the only problem I'm aware of right now, but it really does seem to affect EVERY unit type.
