I tried to edit and rearrange some exits from the Nimbat Village. Adding them is fine, but trying to re-order them changes the moved exit to duplicate another. Leaving the room via another exit and returning a couple times got that to render.
But then I set one exit hidden, and another exit disappeared entirely. I unhid the first exit (d1) and now exit d2 is gone, replaced with a duplicate d1.
So now Widget has no door into her den.
Tried reloading the client and leaving/entering the area.
Edit: I can still ‘go d2’ to get into Widget’s den.
