Hello,
After rescuing Rugan, I cannot move his token and just get "No path to destination". I cannot leave the area because it says we need to wait for him as we approach the exit.
Hopefully you have a save from before you got him. The only solution I've seen is that you can head for the western exit immediately and he can go that way. Otherwise you're stuck until they patch a fix.
I am having the same problem. I rescued Rugan and didn't understand how to find the west exit. I explored the rest of the swamp; when I went in the cave he spawned there, and later when I spoke to a character near the witch's hut he spawned there. I finally found the west exit but he is stuck in the swamp and I cannot leave the swamp. I hope the Dev's read this!
