when switching between crouching and walking/running i suddenly realized that my char started to run like in a nightmare: frantically while making almost no way
when pressing C again i realized my char made the crouch walking animation but in doing so making double the way. i took me just moments to understand that somehow suddenly the animations swapped in the middle of me going from crouching to walking to running going back again to crouching.
i was not able to re-create it nor was i fully awar how it came to be, since it took me some moments.
only thing i know I was swtiching quite rapidly between crouch <--> run/crouch <--> walk <-->run when it suddenly happend
it's also possible that i experienced right at the moment of the "switch" a short lag (maybe a server lag that didn't register me going into crouch position)
i also used the latest swedish stress server at around 20.00 CET 30.12.2017
