So as a forum regular I'm just used to hitting the "Jump to last page" button on everything. It works fine on the main forum, but when using in the clan forums, it sends me to page one anyway. I tried in multiple alts, in multiple clans.
Here's a gif of it happening in my TJC alt, while leaking a bit of a YAFT.
I've asked around on Discord to see if someone else has the problem. It appears Samuel Vimes (night's watch) and Sai Kurogetsu (juggernauts) have the same problem. I'm assuming it's a little bug that showed up with the posts per page change (from 20 to 30).
Edit: Great Expanse (hydra) seems to have had the same problem since always. This has been recent for me, at least. But seems it's a little deeper.
