Can't join friend's Co-Op game. My experienced character disappeared.

Here is the error message that pops up when I try to join her game with a new character. My previously played character disappeared as well.

She also has this problem when trying to join anyone else's world. We both have the exact same mods, and they are in the correct mod folder.

We figured out a solution to our problem. We had to completely delete the SpaceCore file in our mods folder and reinstall it. We kept replacing it with the most recent version but there must have been some corrupt data or something that was not being replaced or deleted.
