I recently have been playing Costume Quest 2. I'm about 8 hours in, taking my time, being meticulous about finding everything, etc.

I was playing on my Series X the entire time and achievements were unlocking properly.

I switched to my One S upstairs and continued playing. Got the last combat tip from Corvus - no achievement. Tried reloading. Same thing. Moved on.

Progressed further to interact with the two statues in French Quarter: no achievement. Went to get my last treat card: no achievement.

I tried switching back to my Series X. Re-installed the game, rebooted the machine, everything. No unlocking, even though all three situations above are achievement goals.

I don't believe this is an Xbox Cloud issue as Joseph has suggested. I bounce around all the time and have no encountered any issues with other games. This is a Double Fine issue.

Now I don't know if I want to restart the game and play through everything again. I also don't know if I want to fire up any other DF game at the moment if this is going to be an issue with other titles.

Over half a year, and it still hasn't synced. My issue is with the Keep Your Shirt On achievement, which is my last remaining one. I spoke to Norma after collecting everything, but the achievement never popped. The same thing happened with the one where you need to go back and talk to Nona at the end, but the prompt to talk to her was still there, and it eventually worked. Norma's dialogue prompt disappears once you talk to her, so if you don't get the achievement then, there's no further way to repeat the talking action to get it to work.

I am missing “Jung at Heart” which is supposedly story based and not missable. It’s the only achievement I am missing not allowing me to 100 the game :(

I have put many hours into the game and it's probably been my favorite release this year. However, I have had a lot of problems with the achievements unlocking. I have about 10 achievements that haven't been unlocked related to the story. Is there any chance that they will unlock, or do I have to replay the whole story on a new save and hope they unlock the next time around?

I have put 50 hours in this great game and have the last 2 story based achievements locked although I completed the game. There are also a couple like buying all the filters that didn’t unlocked although i have purchased everything in the game.

What can i do to resolve this? Can you confirm why STORY BASED achievements are not unlocking days after beating the game?

i just installed the game today and cannot get a single achievement to unlock. they dont work at all.
i tried reinstalling and multiple save slots on xbox series x and pc.

I am playing the game through gamepass.

I beat the game and I'm missing 4 achievements as well, 3 of them are related to finishing the end game levels and 1 related to upgrading your powers. This is quite frustrating considering the game has been amazing

Issue remains, last few story related achievements failed to unlock for me last night, been using Quick Resume without issue until then. Tried a full system reboot today and it has made no difference.
might try reinstalling the game later.

Still bugged. Missing progression on some achievements I had gotten 2 weeks ago, as well as bunch of end-game stuff. However, other achievements have popped since then - IE it seems like only some achievements had issues.

Same issue. Missing Mentee Fresh and Everybody Hates Socks With Sandals even though I finished the game. On original Xbox One.

After 100% the game I found out I'm missing the bobs bottles completion achievement and starting up the amplifier

I just bought all of the pins in the game after I unlocked all abilities. Achievement did not unlock and only shows 30% progress.

I did not receive the achievement for completing Psi Kings Sensorium. I am on Series X as well, it may be an issue with Quick Resume. I have avoided using it since I missed the achievement and have not had any more issues.

I am hoping that there will be a fix that can unlock the missed achievements. Any word from Double Fine about this issue?

Yes! I’m on the Series X and have the exact same problem. Is there still no fix for it yet? I’m missing like 6-7 achievements I should’ve gotten
