Unable to "complete collection 1.0" --> 145 of 146 unlocked -> missing only Greatest Jubilee

[Fex]

I've two achievements to unlock.

• Complete Collection 1.0 --> which I cannot do, since I am only missing Greatest Jubilee
  
• See the Final Fireworks -> which I cannot get before I get Collection 1.0

I've tried re-installing the game and starting ENDLESS mode run. No help.

Did you beat the final boss?

edit: oops forgot you need to unlock the stage to beat him first. I'm assuming you've unlocked inverse mode too?

[Fex]

Yes, inverse is unlocked. I don't know what happened, but after unlocking all the secrets (15/15), the final level now appeared and I got it completed.

The joke is, I happened to have SEAL on Greatest Jubilee when it unlocked (saw the fireworks) and replaying the final level won't unlock it either. It's still 145/146.

Achievement side it's unlocked, but I still don't have Complete Collection 1.0 done. I think this is a bug and only way to solve this is an update that would fix it.

Try the spell code from the other discussion? https://steamcommunity.com/app/1794680/discussions/0/3787002282772523553/

That link takes to this discussion. :)

The Seal didn't prevent the Fireworks from unlocking, I just had to pick it up once. Currently on that run. Could quit, but thought I'd finish it. I'm ...confident it should complete now.

I have this bug, did you solve it?

[Fex]

I'm not sure what unlocked the final level (it will appear on the top of the level list). It simply wasn't there.

What I did was:

- I unlocked all the secrets (used codes for the ones that I hadn't played)
- I started the game in ENDLESS mode for the first time
- I changed the game from Steam Settings to include public-beta (there wasn't any different public-beta client though)
- I started a run with all of the tick boxes set on for the level

...after all this, the level just appeared on the top of the list and I got everything done.
