Regarding the identity of the Vehicle of Doom, the cat was out of the bag way back when a dev slipped that the cause of the crash was 1) a vehicle that was already in 2.1, and 2) was present in all three crash maps (Cobra, El Al, Supercharge), plus 3) had "little alternatives" in said maps. Since Kübelwagen was everywhere and not causing crashes, it was enough to do the math. Of course, common sense told not to spell it out if you couldn't figure it out yourself.
Too bad, I miss firing at infantry with the ZW36 from a hull-down position until a fighter strafed me to death.
