This is fixed in this next update. It'll autofix too since we placed the variable for the Cafe during the screen where you Exit or give a Key. When the update drops next week on Public, just load up the Quest and try getting the Key again
No this was just me noticing a quirk with how that worked and the possibility of it locking the quest. I worked around it in both my playthroughs.
also yeah, doing a second playthrough to try the cannon/pirate mastery path but also to have a character to do both all lovers but also the corruption only characters.
... cannon does not feel very good to use. I don't know if it gets another ability that isn't just the one that buffs the first cannon ability but so far it's FAR worse than just canes.
Canes: have better damage, are actually useable early game because cannon skill just cannot compare to knights slash, feels like they have better accuracy but it's probably just the higher damage vs enemies defence, better group hitting, less annoying to use because you don't need to keep pressing F1 to keep using the buff... I really hope cannon gets something interesting in the future.
