Threadmarks not linking correctly

[Eeffoc]

While searching for a threadmark in Cambrians NSFW oneshot thread (Specifically Like So), clicking on Survival of the Fittest Pt. 2 - Misc Manga, leads to the wrong page. The actual threadmark is the last post on the previous page. This does not appear to happen elsewhere, but I am not about to go hunting for last-post-on-the-page-is-a-threadmark-situations. I do not have anyone ignored, and I can't think of what else might be the cause.
The simple solution for finding something like that is ofcourse to simply remove the part of the link that indicates page number, as the link will then automatically reroute (at least from the user end).
Example:

Busted threadmark link: Hand-changed link: Actual link then rerouted to:

Edit: Randomly found one where it works correctly: Sinereal's Wandering prince chapter 13
