GMSC Tornado Map Series [Classics]
No Demo Tornado
Once you spawn in the gm_tornadohighway map, you expect the message:
"No tornadoes will spawn in 8 minutes after demo tornado. Manual buttons and pause buttoo ns unlock in 8 minutes."
Well after that I have waited a long period of time and the message does not appear and neither does the demo tornado. What can be done to fix this?
