So I was in the thieves hideout in a part with sand that pushes you like a conveyer belt. I went through the door up and link jumped way up in the room. I then tried to go back but there was no door back. I hit some spikes at the bottom and got warped back to the old room I was in. I went back up again and it was a different room and link couldn't use magic powder, arrows or any projectile like that. Also link was invincible, then suddenly I died...wtf?
