It bugs me to an unreasonable extent when Doomworld's forum software claims I'm online when I just logged out, usually due to my internet connection shitting out when I'm logged in. It doesn't matter at all and it fixes itself after like 10 minutes, but it messes with my brain.
Also when it says a post I made 5 minutes ago was posted "Just Now", and when it doesn't show up at all when I'm not logged in for a few minutes, etc, etc. Forum software designed in a lab to mildly infuriate me.
