Just ran into another minor bug.
Playing with just the Princess and Dragon expansion, using 3.2.0.
Placed a tile with a portal. Placed a meeple elsewhere. Then had second thoughts, and used Ctrl-Z to under the meeple placement.
Now, I can only place the meeple on the tile played. After the Undo, it stopped recognizing that the tile had a portal, so I can no longer portal to any valid location.
