Nexus Clash

Being hidden before taking a portal to the Halloween Mansion spits you out in the mansion pocket space hidden. As a consequence it's currently possible to be hidden on the portal tile in the mansion, which otherwise has the hide button disabled and a base 0% search chance. Effectively rendering you unfindable without barring sixth sense or pets or other such specialized skills.

I've changed the tile so that there's a search chance there, so at the very least it's not abusable. Figuring out the portal thing might take more work

Looks like this was fixed a while ago. Event bending now unhides as of three months ago.
