Re: How to efficiently figure out which mods don't work?
@mnmski11 For questions about Tray Importer the best help you can get is probably to go to their forum and ask/read there. I can't link it, since it has third party downloads on it, you have to search for it.
If you want help with your gallery issues, could you please explain more? Has it never worked? Do you have a child account? Do you have the Legacy Edition?
First make a new folder and check if it is accessible there first. Here is how. Don't move anything back until you have tried.
Description on how to make a new folder:

Also do a Repair for good measure, after you have made a new folder. Here is how: Origin>My Game Library>The Sims 4 icon, right click and pick Repair in the menu.
