I was about to ask why we can't strip in Scenario mode. Though I think the indicator of where the key is located in Locked Out is missing since I tried to explore around to look for it.

The indicator in Locked Out was removed. I wanted to experiment with having it removed to encourage more exploration.
Stripping was removed in every other scenario mode to better differentiate them from Exposure Play. Stripping also doesn't make sense Locked Out or Get Dressed, and Streaking is meant more about streaking than stripping.
