I am honestly not sure if this is a glitch or an intentional aspect of the game, but the forum respect total listed my profile only increases on uproves gained from me posting a thread. Me replying to another thread or my own thread and getting upvoted has no impact on my respect at all.

You're completely correct, I'll get that sorted

A fix for this will be deployed shortly. You'll see it reflected in scores tonight once the scheduled job has run to update this sort of thing
