Maybe.
I messed up and deleted them. When I run the next sim, I'll try to re-output them, although sometimes when you try to output old boxscores it foobars and goes into past years.

that only works if you keep FBB open with the current league file all the time. close it once, and you can't regenerate old box scores.
it happened to me once that i lost the local box score files, but then i could download them again from the web storage, that's why I only upload the box scores from the current sim and leave the older files untouched
