There's a specific point in Primal Hunts where when you exit a chamber, you get trapped inside the entrance and can't get out. Return to Checkpoint just teleports you to exactly where you're standing. Light Feather or Rolling won't get you out either. This has happened to me twice now and it's an extremely painful bug since you sacrifice a lot of progress to open a hunt.

I advice anyone on the current patch to just avoid any instances in the Crimson Forest since it's likely going to end your run prematurely.
