Beta 3 + opt-in.  New game, Wizard, random, small.

Turn k ~ 3.  South of Athica, I ended turn with a diagonal move across the south of a mountain.  Hence I had no cloth-map sight to the landing hex until I actually arrived in it.

Turn k+1.  The garrulous Wraith with Ceresa's Circle quest was standing in that hex!  Tandis + Wraith are now overstacked in that hex.

• hex showed a (2) above it
• wiggling mouse made hex toggle its display between Tandis's group and the Wraith

I walked 1 hex off the Wraith, then talked to the Wraith.  It gave me the Ceresa's Circle request.

• our mistress the Fallen Enchanter (haha) ... you're the son of the guy who beat her, we don't trust you
• bring us 3 flawed rubies
• Game engine imprints Ceresa's Circle on the map (leftward of Athica)

Then I moved Tandis to the end of his range.  He was still showing the (2).  And there was still a Wraith co-located in his ending hex.  (I have a save file here, for turn k+1.)  The original Wraith was still where I left him, just south of the mountain (and now 3 hexes left of Tandis + 2nd Wraith).

Turn k+2.  I moved Tandis SE to a weak monster ring, won, then stepped SE to clear that monster ring.  The 2nd Wraith stayed behind.  Now there are two Wraiths on the map.  Is this intended?

At end-turn, both Wraiths walked toward the Ceresa's Circle square.  I guess they want to stand there (and wait for me to bring the rubies)?  The 2nd Wraith was still in Tandis's way.  Bumping into him opened a pop-up: "Try again in 23 days."  So it seems that I can talk to either Wraith to finish the quest.

Are there really two Wraiths that just happened to be 1 Tandis-move apart from each other, so that I landed on both of them?

I'll upload ticket + save file after some wbb.
