I know for sure I have more than a fair few number of items in the 'unsorted' section of my WL.

[uel=https://subeta.net/wishlists.php/504525/0]Nothing is showing up there though D:[/url]

Theres other items I want to add, but I keep getting told that theres too many items in the unsorted category, and it wont let me.

Any ideas on how to fix this?

Make a new category and switch it to your default category. I think that'll work.

Somehow the EpiCon category got made the default, and seems like everything went there D:
