Ratcatcher's Guild was founded twice early in a recent game of mine. First it was founded in Innsmouth of the Lanun, which I had explored and could see. Perhaps 20 turns later, it was founded again in some other city I could not see, but I noticed that the Guild icon was no longer on the Innsmouth city bar. Playing under Living World setting, perhaps that is part of the issue.
I have started multiple games and played up to 100 turns or so trying to catch early game bugs, and with the Barbarian World option enabled, I have yet to see a single Barbarian city.
Looking very promising so far. Thanks, Kael and team.
