Yet again a plea for help

Ok, here is whats happening. In my Castle Wars Map, a very intergal trigger is malfunctioning. Here is how the two triggers go-
The first

Event
-Map Initilization
Action
-Add Castle 1 to CastleGroup
-Add Castle 2 to CastleGroup
(and so on)

And the Second

Event
-Player One Red types message -castle as an exact match
Action
-Unit, change ownership of random unit from CastleGroup to triggering player and change color.
-Set Castle as Ownership Changed Unit
-Remove Castle from CastleGroup
-Wait 2 seconds
-Trigger Turn off
-Trigger Destroy

Care to tell us how it is malfunctioning?

You should post the real trigger to get better help. Just copy and paste it.

Select the top of the trigger (Above "Event") and press Ctrl+Shift+C (To copy as text). Then you can post it here. I think it shows better if you put it into the box.

Castle Selector
Events
Player - Player 1 (Red) types a chat message containing -castle as An exact match
Conditions
Actions
Unit - Change ownership of (Random unit from CastleGroup) to (Triggering player) and Change color
Set Castle = (Ownership-changed unit)
Unit Group - Remove Castle from CastleGroup
Wait 0.15 seconds
Trigger - Turn off (This trigger)
Trigger - Destroy (This trigger)

Ok, the problem is this; whenever somebody types -castle, if someone else has gotten the castle that they randomly select it will change users again, leaving the first person castle-less. This should not happen, however, since the second trigger should remove the ownership changed castle from the group.

The only thing I can see wrong would be this

Set Castle = (Ownership-changed unit)

It's only for events triggered by "ownership changed".

Try this

Hope this works.
