I need some testing, please (connect four)

Hello!

Lately I've made a map, the basic connect four -game. It can be played by 2 human players normally, but the main coding part is the AI I've implemented.
The problem is that sometimes the AI makes a move which is impossible.
All I ask of you is this:
-play the map
-have fun
-or not
-and if that bug shows up (you'll notice it), please press ESC ingame and send me the screenshot so I can pin that bug down.

The game is played with the arrow-keys: left and right to toggle and down to make your move.
If the bug doesn't show up - congratulations, you've just downloaded a connect four map for you and your friends.


P.S.: Sorry, the little text which is in the map is german, but that should be no problem at all, it's really self-explanatory.

Have a nice day!

Just tested it and got a bug; is this what you mean?



Basically, I was just playing with the friendly AI and then suddenly the blue "chooser" unit appeared for the AI at the very top (which never happens) and the game is then stuck because I can't go and the AI won't go.

Thank you!
The blue circle appears always at the top, but it moves almost instantly (if not bugged).
I'll look into the map anyway.

wow cool!
