I've noticed lately that my BBB mod suddenly stopped working. I downloaded it like every other time but suddenly it showed me it downloaded incorrectly. One second ago I noticed why! It says next to the file that it's a sims 2 mod. It might be because I changed my sims location from disk C to D where my sims 2 game is. Does anyone know how I can change ALL the mods back into normal packages that will work in my game?

Hello. You'll have to sort out your Sims 2 and Sims 4 package files manually if you've mixed them up. If you dropped just a folder on its own and didn't mix it in with Sims 2, just move it to the Sims 4 documents folder.

Make sure your game points to the correct location.

You can use the Sims4 mod manager to locate your Sims 4 mods to help sort them out if you've mixed up your package files
