Class bug

Ive noticed sometimes wen ur trying to pick a class, it wont let u take it, ive clicked the AM class a couple times but it wudlnt let me take it , ive clicked every other class still wouldn't let me take it

i had that once but i selected a npc or some other player's unit then clicked the thing and picked the class i wanted and that worked for me

I noticed that today when I pressed something else then the helicopter.
Couldn't get it back so I could choose class.

Never happened any more thou.

Not that big of an issues unless you're competing with someone for a class. Just click something or someone else then click helicopter again and choose.

tried that b4, didnt work

Selection and De-selection usually does the trick. It's also helpful if you don't select the helicopter yourself, but let the game select it for you (about 1 second after you have mouse-control).
I'm not sure what's the cause for that, so I don't know how to fix it, yet.
