Problem is not local to the outback. Here in florida when I hit F1, "trainer Activated" but the moment I load a save game, it CTD. Thank you for all you do.
Just played with trainer "PATCH 01.21.2014".
Trainer crash game @ main menu activating F1.
Work when activated in-game from "Continue" (saved game should also work).
Tested: Unlimited Health, Quick Sprint Recovery, No Reload, Weapon Overheat, Vehicle Damage, Instant Powers.
All vehicles I drove where immune to damage, no exception
