Well I have yet another question.. Does anyone know if it is possible to stop a probe from being able to pick up a vespene tank or anything else that probes usually can pick up?
Disable the powerup and workers won't be able to pick it up. It will become cloaked though.
or give it to a computer player and run junkyard dog script. at least, thats what i've heard works.
thanks zeratul that worked perfectly for me.
