It depends. Typically we'll do as many as it takes to get any bugs that we feel are game-breaking. No one wants to get stuck and lose progress for example, so we look for things like that. Small bugs that don't really "block" the game from continuing, we'll either add to our next update or do a hotfix patch if its decent enough (like the black screen on Android we ran into last time update). On example of a bug we're "allowing" is if you go backwards from the beach and you go back into the ripped outfit, there's no way back into the bikini model currently. Aesthetically not as pleasing to some but it doesn't stop the game from progressing.
Typically its 2, but by the very nature of game dev, when you fix a bug, you allow the code to reach different areas it was previously breaking before. So you might introduce more bugs but fixing others lol It's not an easy process!
