I’ve not been following this forum so sorry if this is old but a quick look at known bugs didn’t list this. A few days ago I saw a Parnell who apparently never needed to reload and simply fired continuously with the Autoshotgun. I don’t think he ever used super-soldier either which was kind of weird and he continued firing long after monster was dead as if his trigger was stuck.
Couldn’t tell if the bug was my client continually playing firing animation or if someone has found a glitch to make the game think their magazine is continually full. I tried asking in the lobby what everyone else saw and they all quit without comment.
Edit: Oh, this was on PC btw.
