Whenever I try to load a custom schedule a pop-up appears saying an error has occurred. Has anyone else come across this?

Likely a file formatting issue, incorrect values, or doesn’t have the required number of games for the type of league. If you post the file, could look at it and also indicate what your league setup is (number of teams, etc). You could look at my real world mod for an example of a working schedule file.

This was fixed with the latest update, I was looking to do an 8-team, 10-game schedule. It works but the program will still take a bye week into account.
