Did File Verification Reset Achievement Progress?

I’ve searched all over and can’t find any thread about this- my game experienced a crash whenever I launched myself into the middle of the bibberbang field and they all started going off. Not a big deal, submitted the crash report and ran the “file verification” like it suggested, then loaded back up and went about my business.

I immediately noticed tutorials were all reset. Then I popped into camp and a mysterious second Adventurer’s Chest was there. I quickly checked my settings and it had multiplayer joining turned on again (where as I had it off).

After finishing at least one background quest and reading multiple new books, neither of the two achievements that keep track of those two things went up at all. 64 books before, 64 books after, but I KNOW that I read new books.

I’m frustrated because I’m worried that it’s screwed up my file and I’m terrified of some game-breaking bug appearing 100 hours in because of this , and I really don’t want to restart this many hours in! Has anyone heard of this happening?
