maybe a trigger prob... but maybe not

I got a problem here, I don't know if this because of triggers or not. I think it's not.

trigger action "unit - Issue order targeting a point".
I want a unit move to point A, without ignoring the enemies, so I used "attack-move" as order.

Few weeks ago, I tried using this trigger with unit that have abilities... it use the abilities to heal itself or to attack the enemies.

Then few days ago, I do some change here and there, including unit data, triggers, gameplay constant, etc. Then that "attack-move" trigger won't work 100%! they still move to point A, kill some enemies in their way. But without using their abilities!

How come? What could possibly prevent them to use their abilities? I tried to figure out by myself, well... failed.

Did you change the owner of these units? Even if you didnt, the AI does tend to do weird things, sometimes it will use abilities on it's own accord, sometimes it wont.

Yeah, I change the owner...

But it still working few days ago... I just make change to unit's level and Stat - xxxx in object editor, and some in gameplay constant... then... voila! the trigger won't work normally. I use unit from campaign editor.
