Don't know if anyone else has had this happen but quiet often my weapon abruptly stops firing or won't fire at all. Fast firing weapons like rifles jam (except the heavy machine gun) or slow firing weapons like the shotgun and hand cannon don't fire at all. And yes there was ammo in the clip. Only happens in the crucible and most often while aiming. Most likely a lag issue but an oddly consistent one. Otherwise good game by game bungie with a lot of potential. Comment if you have had the same issue.
