Hi,
thanks to the posts that you can find here, I found and fixed a MAJOR BUG:
* the first time a barbarian tribe evolves to the Kingdom/Empire status, ALMOST ALL Hordes (even those belonging to other barbarians) vanish within one year.
This bug has been caused by an early delivery of a change under work, during the release of the Patch 1.07a, intended to solve the game perfomances drop caused by the serial-key-copy-protection.
So I URGENTLY fixed the bug and built a new Patch 1.07b, that is for AgeOD version only, of course.
You can temporarily download the patch here, waiting for the "official" publish inside the game site.
My apoligises again!
Thanks,
Calvinus.
