I'm playing on the PC so if anyone knows a console command I would appreciate any help.
I got hit with an arrow escaping the starter dungeon and it hasn't disappeared yet. I've reloaded saves, slept, dropped all my stuff and completely healed myself but nothing has worked.
I had this problem but after a couple of in game days it wasn't there. Dont know if it was because I fought something else that shot arrows or if it just went away.
The solution is to get shot with other arrows. I had the same problem OP... go find a bandit archer and get yourself shot. The new arrows will replace that one. svcks yeah.. hope to god they patch it soon.
