Dunno what the heck you three people (out of 360,000-ish others who aren't having a problem) did to poor Grumpy, but he's (obviously) secretly deleting things off of your lists just to mess with you.........
could you please be less aggressive?
@topic: if we assume there's an issue with the follows, could also be a database corruption or some maintenance-related hiccup around when you followed it, but these would be more of an one-time thing and likely to be noticed by more people I think... then again, hard to say if or how many more people wouldn't ever notice it happening because of relying on follows to remember for them. or some rare stray bug in IPB that requires some additional conditions to fire (idk, toying with follow/profile settings? some specific edits to the comic page data?) - that one would likely also affect thread/group follows if not for hardly anyone using them.
after digging through a few ancient disappearing follows reports, I got an idea and checked if maybe changing the main comic title (which works as one of IDs) does anything (since the few examples that got mentioned had their initial title changed), but that in itself did nothing to the amount of following users, at least in my test group.
