He ported all the vehicles somewhere on the map. (location: 77 36)
I wrote this number in chat "123456" when this happened. It was arround 13:18 gmt+1. With all the cars gone and helis we also lost load of gear because we were moving all the safes.
When vehicles were ported there they started to explode because there were 1000 of them stacked on the top of eachother.
When he ported every vehicle he also ported all the players and killed them.
Another rollback would be nice.
