I was under the impression that one of the recent patched had fixed the sudden player ratings drop bug, but it appears to still exist. This is with 9.2.2 in an online league. The online league is a much faster pace than normal online leagues, so the entire season happens in one night.
This happened to one of the owners in the league to their prize stud youngster (24 year old):
Ratings prior to the season:
Ratings after the season:
And if anyone is interested in the "Real numbers" from the editor...
Ratings prior to the season:
Ratings after the season:
This league has injuries off (even though due to the lefty/righty split after the fact, this obviously isn't injury related anyways).
From the looks of it, this bug almost seems to be somehow occuring when a player gets "too good" in one rating, and it increases beyond 250/250. Instead of stopping at 250/250 as it should, it seems to wrap and start over again at 1/250.
I have league saves from before and after the season as well if they would be useful.
