Lately me and my friend have a problem with a random bug... sometimes you cannot go prone (it just seems to "bounce" you up and down), and you can't sprint either. I have had this happen on 3 different servers (2 playing Karkand, and one playing Wake), and this happened to me and my friend at the same time. Is this widespread or what? Thanks.
This "bug" depend of the server you're playing on... (You can sprint but once your sprint bar is empty it don't reload)
try on others servers and it will work.
