I encountered a rather unusual phenomenon. On day 137, Torgrim had a stack of 12 griffins and 20 aerial units in his army on the map. On day 141, all of this successfully converted into a starting army (i.e., there appeared centaurs, dwarves, and elves instead of the two stacks). Torgrim's level did not decrease.
I'm attaching the save files. Passwords:
