Ok, so I used to make lots of UMS games for my friends and I, and arguably the main component to having a computer ally was the 'share vision' trigger. Well, we recently started playing again, and I noticed the trigger is gone, literally just gone. When I open up some of my old maps, the trigger is still saved, but when I click on the trigger to see the pull-down tab, the only options there are 'send all units on random suicide missions', send all units on strategic suicide missions', and 'switch computer player to rescue passive'. So, WHERE THE HELL DID THE SHARE VISION TRIGGER GO?????

It's called "Turn on Shared Vision for Player x".

No, that's what I'm telling you, it's just gone... Condition = Always, Action = RUN AI SCRIPT, and there are only those 3 options there. It did not used to be this way, so wtf happened?

Staredit has only very few AI scripts.
Use an advanced editor like ScmDraft 2 to access them all.

HOLY SHIT I completely forgot about this - I used to use SCMDraft2, can't believe I forgot. It was really blowing my mind that the trigger wasn't there LOL...Thank you so much NudeRaider!!!!
