So I'm on a second playthrough and there seem to be quite a few bugs popping up:
i) after talking to Udyne the quest Sorceror and a gentleman has simply disappeared (neither complete or available). Remaro isn't at Sayuka or anything
ii) Mirke isn't at fort deadlight (but I did attack it at the start and killed a lot of people but I don't think I went in the Court tavern)
iii) the Deck of Many Things was in my game. I visited it once and it has disappeared off the earth.
I'd attach a savegame file except for some reason I am not permitted to upload this kind of file (which is a bit silly tbh)
