Arthritic Units

Some computer units of mine are having varied reactions to commands. They might hesitate 5 seconds, after being attacked, before they respond. Same thing goes if I issue them an order through a trigger. I can't really pinpoint the cause, since sometimes they react instantly, and sometimes it takes them upwards of half a minute.

The only thing I can think of is that the computer is designated neutral, although it's alliances are set up. That still doesn't make sense, because other neutral CPU's don't seem to have this very annoying problem.

Any ideas?

If they are told to attack to a point, they will attack to it, but they will stop when they get into a fight with something. If you want them to keep attacking, make a trigger that makes them attack every 5 seconds, which would make them fight more often. Try it.
