Where are my polemistes gone?

Really they didn't disappear from game, but from the moment i built skirites (i think), in my training unit box i hadn't no more Polemiste but i had an upgrade of Enomotia Hopliton and the E. Ekdromon.
So i can still reinforce my old Enomotia units putting them inside town in the traiding box, but i can't do this with my Polemistes. The problem is that i have 4 generals with, 7-6-5-7 stars with only 1 man, the general himself, and i don't like to loose them like ''fighting unit''....

Do someone know if this thing is normal and i have to forget to reinforce my ''lonely' generals??

Polemiste are only available in "Early" (ie Geometric) era, so I take it you've reached the year "250"... if you haven't then I don't know where they went ~D

Ok, i've understood. It's 265 bc, so my Polemistes are definitively gone... ~D
Thanx
