So I used UME to make a mod in order to add a few topics. When I was done, I clicked "Validate project and code", and no errors were found. Then, I clicked "Build expansion mod package", named it, and when I want to upload it on the workshop, or even just put in directly in my mod folder, nothing works.
If it's directly in the folder, an error message pops up, and if I want to upload it, I get this: "error invalid game dev tycoon mod"
What am I doing wrong ?
