for now, i can tell you why it's happening and you can avoid it until it's fixed.

if the schedule file being used has an asg scheduled, it will be reset each year from any changes you make.

goto league settings - > options. click the button next to the file name to open file location. right click and "edit" the file, or just open with notepad.

search for ...type="4... (or is it type="14, include the quotation mark). only one game will be that type, it will show home and away = 0, too, if the other serach term doesn't find it, use that. it's probably around day 100-110ish probably, if 162 game / 184day season.

delete that line from the file, or move it to a day you want it to occur on automatically each year. if you want to manually set it to a different day # each year, you'll probably have to do it each preseason. it won't maintain the date unless you start the season on a specific day, like april 1.

if you do want to just move it, set it in the game first, let it create the new schedule, then export that schedule to a new file. name it and make sure to import that newly made file the next preseason. (name it for the league as the old schedule was named, maybe even rename/move the old schedule file so it doesn't accidentally get auto-selected due to its name)

this will get fixed eventually, so this can keep you working correctly until then.
