Here is a video where Frabj22 got the watch you step achievement, but the popup was missing. Frabj22 didn't have in before and had it afterwards, it just didn't display. You can see the steam notification popping up, but the ingame notification does not. Video: https://www.twitch.tv/videos/2680142128?t=10h21m45s

For reproduction: As far as I am aware, the ingame popup simply never works for this achievement.

This is a zombie bug, previously buried but back from the dead fixed: viewtopic.php?t=82015

Do you have in-game achievement popups disabled? (check the-rest GUI).

If you watch the video, another achievement does pop up just after. So in-game achievement popups are clearly enabled.
