I turned in a bug ticket on this on Jul 26, 2013 22:51:39
This is most certainly a bug! (imo) I glad to know others have noticed it.
I'll use prep league for an example.
At the start of the season the age group for Prep was day 1 through day 40 players
Currently it's set at d8-d47
http://goallineblitz.com/game/leagues.pl*The trade offer page is not keeping up with the aging players. (there is no problem signing a d47 free agent)
*So it thinks that all players now over d40 are too old for the league.
I still have the trail of PMs and replies from EB
If you have a prep team and you initiate a trade with another prep team, only the players younger than day 40 will appear in the lists to choose from. This is true with every league that has an age cap and is why pro trades work just fine (no age limit).
I've been trying to explain this to support since july 26th. (some of my replies via PM haven't even been read yet)
I finally gave up last night, and worked out a cut and sign. (thankfully it worked out and the players involved signed the next day)
