When rightclicking a tile with a sunken ruin on, I occasionally do not get an interaction option, which means my units will just travel to the tile, and I will then have to leave the tile and revisit it, for another chance of proccing an interaction.

This is happening with the new major faction, and has happened with armies consisting of either one of the following: Mastermind, Vore, and a solo Hero. 

I reinstalled the game when I bought the expansion last night (So all files are freshly downloaded) and -all- expansions are active.

So far I'm really loving this expansion btw, great job guys!

I appear to have been sloppy, and have relied solely on autosaves since the reinstallation. I'll see if I can reproduce it on my end and repost the result here.
