I Was Tinkering with My TERRAN WARZ Mod (Dont Ask Me For It, Its 23.6MB)
And i Found Out that if You LockDown a Refinery\Extractor\WHATEVER, And Then Destory the Gas Collector, It Becomes Hallucinated, And Whenever Your select It It Says '' Your Forces Are Under Attack ''

. Can Anyone tell Me Why It Does This? I Am Just So Curious.

And The Refinery\Assimalator\Extractor Blew Up, Just so you know.
