Lately, I've been noticing a lot of old Tigons and Leopons in the TC that have no more heats in them just being marketed as 'Tigon 3m' or 'Leopon with mottled rosette'. Usually old hybrids are frozen or otherwise notified for being trophy only lions [ex: tigon for freezing]. These trades have no such indications and while seasoned players know better than to buy a hybrid without checking it's age, new players do not. [And there's nothing onsite to inform them either]

I think it would be really unfortunate for a new player to buy a 14.2 year old tigon for nearly 100gb only to be told later in chat or modbox that it's not breedable. Hell, even seasoned players might forget.

Therefore, I think it would be a good idea for warning text above a trade that says something like 'Warning! One or more lions in this trade is too old to breed!' In red text.
