So I was trying to get her to the Child Tourist as I suspected I could sell her for a really good reward.
Killed her, brought her back with a WoR, escorted her up to the surface near the village. All well and good. But when I tried to move off the cave entrance square I got the message that one of your allies can't cross this terrain.
I managed to work around this by taming the entire tourist family, bringing THEM to the Underwater Tunnels, and chatting to the Child. Was this intended or should Lobh-se be able to enter New Attnam?
