well one day i was fiddling with a map and i thought about putting two beacons one that disables a unit and one that enables a unit
after crashing sc many times i got it to work and here is a replay of it
its diff than the normal way of cloaking units because u can look at it while its disabling and enabling and it doesnt move
i modified the map so the computer controls it and it worked once with the right wait times but i tried it again and it crashed, its not consistent
