I was there, I dunno why it happened but falgs can get thrown out of bounds at times, I tried.Hey, was in a game about five minutes ago, chattyloid had the flag but got sniped and the flag went through the OOB barrier on Frostbyte.
It has nothing to do with height.I was fooling around last night in an empty server, ended up getting the flag out of bounds, but the only way i could do it was to go 200+ off a hill and toss it over the top, which is nearly impossible.
