Not sure what you mean by "clicking" but yes, I have pressed the mouse button many times, so that the power in question is DEFINITELY queued up. (the game sometimes does not register the power when you click only once for some reason)I've tried queuing it just once, twice, three times, four times.
No luck. Kreia still just runs up to the mines and gets herself blown to bits. The only thing I can do is use ranged AI and have her blast, set it to stationary (in which case she does nothing), or set it to jedi support (in which case she uses some random useless force power a la force drain).
I cannot have her use a specified force power when I am not directly in control.
That's really annoying because the AI has no idea what powers to use in what situations under "Jedi support." it just kind of randomly cycles through all her powers.
