Unresponsiveness with command buttons and units.

I have a problem with unresponsive command buttons and units in my map. What happens is during random times in the game, when they click on a button in the command palette when they try to upgrade something, nothing happens. Same thing when a player orders a unit to move, the unit response sounds are played, but the unit doesn't do anything. Since it happens randomly, I have no idea how to find out what's causing it. Any ideas? :(

Seems like you have some memory leaks to me, look out for points and unitgroups you don't delete. (At least, thats what I think.)

All of the memory leaks have been dealt with. Another thing I should probably mention is that when you unselect and deselect the unit(s), they'll work normally. This behavior happens throughout the game and at random times. It's just really annoying having to unselect and deselect units to get them to do something and I would really like that to be removed. :(

Hmm... I've seen a similar thing in night of the dead. I was never sure what caused it.

On another occassion i had an almost identicle glitch when I was trying to use a specific triggered ability, based I think on sentry ward. The unit casting it would always freeze up as described. That only happened with the one ability, and I cleaned up the code & changed the ability and now it doesn't happen.

Not sure what's going on, to be honest.

Have you tried unselecting and then reselecting them with triggers? See if that works.
