Hello, curious if I am unable to unlock this due to fully completing most areas, I have a few I've been entering and quitting either tower upgrades or whatever I can do but I cant seem to find the last 2 out of 34. Am I just screwed?

I need help, because I think I've softlocked myself from getting all achievements in Decision 2, on a 90% completion save. What happened: I've purchased all weapons, got the achievement for having all weapons, and then quit the game. When I came back, I had all my weapons, but the achievement was missing from the list. I've completed a stage hoping that it will trigger a re-check: nope. I've gotten a new achievement hoping that it will trigger a re-check: nope. I can't purchase new weapons or skills as I...

can''t complete achievements in game

Is this some kind of bug? I cleared the ground and tower on every map section

I have all other achievements, but Completionist and Mega-completionist are still locked. Any idea? I completed medieval on another pc, I hope I don't need to get everything again on the same pc...
