World Adventures and mods
After installing World Adventures, I first checked if custom content was still working. Objects, skins and clothes all still seem to be working. Mods however is a different story. For example my buyable Life Fruit stopped working as well as several others. Censorpatch still works though, but it's clear that a lot of mods will need to be updated.
