That's a new bug.
I have a friend from this forum, Peter Ren, and saw his post (in a TE fb group) about a player he had - an announcement for an extra season.
He was 35 y.o.
Never saw that before.
This player mysteriously gone this season.
So it's a new bug.

* For all the managers, if you see this case, keep that player in your bench for the season's maintenance.
