For reference, I don’t speak English, and this post is translated.

I have 32 out of 44 Steam achievements unlocked, but some achievements are not progressing.
The achievements A Helping Hand and I May Not Be Good at It After All… have stopped counting, and the achievements Strider and Well Earned Rest haven’t unlocked at all.

Here’s what I’ve checked so far:
Steam overlay is working properly.
Verified the integrity of game files.
Tried completing them in co-op mode.
Died from an animal and respawned to try completing them again.
