I couldn't find anything regarding this in the wiki/forum, but pool 22478 has two duplicate posts listed: 2519590 and 2566323. I assume it is to keep the same sequencing between the two versions of the comic, but it means the bar at the top of the page will go from page 13 -> 14 -> 5, making an infinite loop. How should this be handled?

Adding duplicate IDs to the same pool was definitely the wrong way to go about this. I've gone ahead and removed them. If desired, the pools can be split into two versions and named accordingly with suffixes like (combined images) or (individual images) - linking to each other in the pool description - but I don't really think it's necessary since it's the same combination of images. Someone can just make a set if they want a specific order for the individual images version. For now, I've left the pool as-is except for removing the duplicate IDs.
