So woke up this morning to do some last minute tweaking before we demo our game off tomorrow and somehow in a haze I decided it would be a grand idea to update unity/playmaker/ngui, doh. Then before testing to make sure everything worked I tweaked a few cosmetics on the game, doh again. Then I built and ran it and now for some strange reason none of my System Event - MOUSE DOWN events fire off my NGUI buttons. Previously all this worked, unity must still be seeing the MOUSE DOWN events because the other OnClick triggered actions, like offset/scale, fire.
Tried switching them to Mouse Pick and they don't work correctly, will probably need additional tweaking with that. If there isn't an easy fix to this I guess I can do that but I'm guessing this is something simple I am missing.
Any ideas would be greatly appreciated on how to fix this or what could have caused this.
