This update changes the way saves are handled. Savefiles are now about 1/10th the size (sometimes smaller) and should be able to handle, in theory, 10x the amount of seasons than prior before having issues. Unfortunately, this change breaks any previous saves and you will lose them. This does not effect custom roster files. This one of the drawbacks of early access that sometimes changes like this have to happen and I hope this can be kept to a minimum.
Savefiles are now compressed before going onto your harddrive. This causes save times to be longer, and, in turn, load times to be longer when it uncompressess. This is not a perfect solution and I am still hopeful the initial cause of this issue gets fixed so the savefiles are even smaller and load times will be faster.
