Autosave ignoring instructions

[Scarecroww]

This is probably a bug but I first wanted to check if someone had similar issue and if there is actual reason behind it. Basically I have auto save set to "After matches", and for 6 and a half seasons it worked just fine. Now suddenly it randomly started autosaving, can't tell the pattern yet but it happens mostly on the same days as match (soon after the regular auto save), and a day before a match. Also I had someone join my game today or something(my match wouldn't start as it was waiting for someone) I never used any online features so not sure what was that about and maybe it's related. Help anyone?
