[1.0.1] Escort appeared only the second time

[Nimmy]

This is probably not meant to happen.

First time, I went to Dreadfell lvl1, the level was very short. Just one door to open, and the exit was there, that's it, nothing else on this level. So I dug a bit, and as expected, I found the rest of the level, killed all the enemies then left for the worldmap (as I had a alchemist potion to get).
I then went back to Dreadfell lvl1, and found, surprisingly, a lost warrior escort on the level.

If you look at the map below, you will see that the portal was in the zone that was not accessible without digging.

Map attached. My character is standing where I had to dig (so I only had access to the part on the right without digging)

This is "normal" behavior, as the escorts don't spawn if their portals are inaccessible. It happens even if they're just behind doors too. Once the portals become accessible, if you exit and re-enter the floor they will appear, as you saw happen. I agree it is kind of weird though, the portals should probably always spawn in accessible locations, I've heard that they can even spawn in vaults.
