Hey, I'm so sorry about that! I'm trying to replicate your issue but can't figure it out. When the elevator door was blocked, could you not just talk to the Reset Frog to clear the way and restart the puzzle?
Thank you so much for your help! I've figured out the issue. Interestingly enough, it technically wasn't a softlock as when the glitch occurs you just turn invisible haha. I'll be publishing the update as soon as I can.
