I've read a good deal of post & threads on the forum, but had something happen today that has me puzzled.
My highest level gladiator hit level 25 today.
Ranking is 1st in Juggernaut.
Record is 111-44-2.
On his Overview page, to the right of his exp. bar has appeared *Retire?* (in green)
it is click-able, but I'm not sure if I should try it.

I though retiring a gladiator came at lv. 50.
What are my options in this?
