It is not as bugged as you think.Definitely needs more patches. I love the robolife games but there are some glaring issues here and there.
Had some untranslated lines throughout.
Epilogue Nightclub is seemingly bugged? so I can't complete the exploration mode to fight the superboss which means you can't unlock the final final scene without the cheat option you can get from clearing the epilogue's main story.
Also the epilogue main story skipped over some listed trigger causing the game to make me unable to clear Emmie's epilogue branch.
If Emmie's epilogue says: "Stay at Home to advance" it actually means "Go Explore all 3 dungeons and fight the bosses in them."
You might be stuck on the Disco Dungeon. At the Event where the thug is dismembering an Android and says to you: "Get Lost!" you are supposed to insist 10~ times in order to piss off the thug, defeat him and grab the keycards. No idea why you have to first get him mad in order to attack him.
For the Nightclub mission, all you need is 500+ Service XP (by grinding nun Alice events, you can do it twice a day) but most importantly you need to visit the Club in the afternoon in order to buy Staff that will protect you from attacks, give you more clients and more revenue.
