in my last play session yesterday, there was a point of the gameplay that i was solo killed by 1 infected, not because im retarded, but the infected somehow trapped me into the ground, in front of him, i couldn't move away from him, i tried hitting it with my axe but the hits simply wouldn't land, tried blocking his attacks aswell but it appeared like he was ignoring it, it looked like some kind of weird desync or something like that, i ended up getting killed by him, not sure what triggered it, sorry about the lack of info.
