i have a map in which i want a probe carrying a khaydarin crystal to bring it to a beacon, in order to activate buildings for current player. However the conditional trigger wont work for powerups in any configuration I try. I have used both 'Bring (specific unit: Khaydarin crystal ) to location' and 'Player (current player) Commands At location'
Any input would be greatly appreciated!

Attachments:

Conditions:
If Current Player brings AtLeast 1 Probe to Location
If Player 12 Neutral (if you make all Crystals neutral later on) brings at least 1 PowerUp To Location

Actions:
Then do this and that.

I think this is how you should do it. I'm not sure.

You could try centering a location on the probe constantly. Then, you could detect when the probe picks up the crystal: when the crystal is present in the location.
I'm not sure this is the right thing to do but it was all i could think of. =[

Trigger 1
[Conditions]
Always
[Actions]
Center location labeled 'location that follows probe' on Protoss Probe owned by Current Player at 'Anywhere' (Make sure the location is so small that the probe cannot move to the crystal without picking it up.)
Preserve Trigger

Trigger 2
[Conditions]
Current Player brings at least 1 Khaydarin Crystal to 'location that follows probe'
Current Player has suffered exactly 0 deaths of 'desired death count unit'
[Actions]
Modify death counts: Current Player set to 1 'desired death count unit'
Preserve Trigger

Trigger 3
[Conditions]
Current Player brings at least 1 Protoss Probe to 'location where crystals are returned to'
Current Player has suffered exactly 1 deaths of 'desired death count unit'
[Actions]
Whatever you want to do to the probe and crystal.

I'm not sure if this will work, as i have not tested it but it should. GL with the map. =]

Just removes the commands at location and make the Khaydarin crystal for All Players.
