Vulcan Island doubled NPCs

[Jahus]

First, thanks for bringing us Vulcan Island. I didn't explore it yet, but I'm all enthusiast at it.

 

When I've first visited, I've fought against Jana NPC (first NPC we meet), but I've gone back to Vermilion to take my team with me. Now, there are two Jana; and both stop me to talk (after-match dialog).

 

 

Just few steps after that, I get double NPC again:

 

 

Only one of them fights me, the other will stop me and the after-match dialog is launched.

 

Now, in fact, all NPC are doubles (Not Chappy, and others).
