Literally the only bug in the entire game (that I personally experienced, at least) was that, after becoming a patron, if you choose to go to Haela and press the "kiss" option, she just asks the question again and the game freezes.
Other than that, incredible game!!! :) I ADORE all the character designs, the writing, the lore and world building, the music, the sound design, the voice acting, AGH it's all so beautiful. Safe to say I will be thinking about this game for a long time.
