Weirdly, this post hasn't been visible until now. Had to actually search for the post: https://lemmy.ml/post/1293377 on lemmy.wtf and then I could comment on it via lemmy.wtf. Then it finally showed up at c/guildwars2
edit: commenting on this post makes it load forever for some reason, but it does go through. My guess is, lemmy.ml is still being very sluggish.
Dunno how long it will take for lemmy-0.18 to be released and for the influx of new users to calm down a bit. Until then I would probably avoid digging too deep into issues like this.
