Re: CAS swatches are messed up.
@skintea Try removing the More Columns mod, the UI Cheats mod if you have it, and any other mods that directly affect the user interface or CAS. Delete localthumbcache.package as well.
If you still see issues, you'll need to test your mods and custom content and figure out what's broken. You can use the 50/50 method; even with thousands of files to go through, finding one broken item would only take about a dozen tests. But be sure to test every file at least once, since you could have multiple broken ones.
