After I activate the windmill, when I go back to the caves and have to investigate now that the acid's gone, I cannot go down the ladder to the pit: no ladder icon. When I go down "manually", I can see a ladder icon downstairs, and I instantly die when I touch the ground, as if I had jumped the 50 meters without using the ladder. If I try to teleport to the ground before, I infinitely fall into the dark outside the game limits. Please solve this, I love this game, I spent 15 hours playing it in VR, and I'd like to finish it!
