Humans have mutant speed, mutants have human speed?!?!?

Ok since the patch, I've noticed that when I'm human I run as fast or even faster than a mutant at normal speed(not pressing G for extra speed). However when I'm mutant, I run at human speed unless I press G.

I've tried uninstalling and reinstalling the game, but the same thing happens. It doesn't happen all the time, but I'd say about 60% of the time I'm playing mutation these speeds are switched.

People keep calling me a hacker but I'm not. I see it happening to other people as well, they're human and I'm mutant and they out-run me unless I press G.

I suspect G4Box changed something in the coding that determines speed of different characters, well apparently they messed it up.
