odd, seems to work now, but I did nothing different when it failed - may have been against a particular enemey in a particular encounter (I can't remember where, but it happened twice). I just remember being 'whoaa!' - I selected the spell, clicked a few missiles for one target a few for another and the one target received all the damage. I always select by clicking the targets on the screen (not via potraits at top) - and that has always worked. Anyway, hope it doesn't happen again
