hello, i’m sorry to reply to your post instead of opening a new one, but i think i had the same problem/bug.
Freecodecamp also crashed, and i simply left it, and came back later.
After i came back i realise the the counter had reset, but since i was starting with bootstrap (2nd chapter) i tought it was normal.
But now, looking at my profile i see that all my previous progress was lost. (https://www.freecodecamp.org/fcc9f26df36)
I should have progress on 15/07 and 18/07 too.
