Character is a Templar Breton Magicka build, PC NA. Frequently, in the middle of intense combat (dungeons, trials, or dolmens) I experience an issue where all spells and staffs stop working and my stamina will not recharge. When this happens I'm forced to run around aimlessly until all my stamina is used up. At that point my stamina will begin to recharge and everything goes back to normal. It's very weird because even normal movement will use up stamina with no recharge. Nothing works until I use up all stamina.
Honestly, for a long time I thought I might have been hit by a spell or stepped in the wrong place. But it sure seems like a bug. I'll be firing away when suddenly nothing works and I'll look and see my stamina slowly going down as I move around. Very irritating as it happens quite frequently, sometimes twice in a single dungeon run.
