Bogus Pmove???WTF

when I get meleed..I sometimes get this error: Bogus pmove used on player 084 df9835 (4) whatever and a bunch of other crap..is it someone scripting? because it's always by the same person, no one that seems like they are playing "legit" I get this area from..wtf is it?

You'll have to ask harSens or PCJoe what that is, I have no idea. But its because you have dev turned on, otherwise don't worry about it, it isn't someone scripting, its something returned by the actual game.

I get this error message myself, whenever someone hits me who isn't right next to me visually. It's the reason people think there are cheaters abusing the new hit detection.

This should get moved over to the coding and bug report section though.

It's no problem, don't worry about it.
I think it's caused from when the entity still has a decently large velocity, but you're trapped against a wall / some object and you're not moving... I'm not really sure though, just don't worry about it, and don't scream "CHEATER" every time you see it.
