Testing on local and only four maps cause CTD on all layers:
Fallujah. ( Worked fine on local after 1.5.4.2, not tested on server)
Karbala.
Saaremaa.
The Falklands.
Two more have different issues that only seemed to of happened on VG server
Assault on Grozny - Stuck on dead screen.
Silent Eagle - Gets to "verifying client data" stage and server crashes.
