1. When the general's garrison is erected (e.g. after transferring) if you have another general window open, the context switches to the general that just finished transferring. This will also happen on co-ops and you can sort of "control" another player's general. There was a very similar bug which was fixed in test - it used to do it for any notification coming from a general (e.g. attacking, going into battle, won a battle, lost a battle).
2. After sending several generals into battle, you can't select the generals already sent (making it impossible to retreat).
As an extra comment, I'd like to add that the constant freezing (3 second freeze every 6 seconds in my case) when the star menu is open is a real killer for me, and the generals issues described above.
