limit on famous battles?

[Hooahguy]

well, i was playing EB as the romani, and i just got 6 famous battle markers in one frame!!!!!
well, one of them disappeared.....


and yes, all of those are mine, and all but one by the same general (the general who you see in that screenshot- somehow didnt get any command stars ) (the one by the bridge was my another one of my generals who died long ago.....)
anyhow, i had 3 famous battle markers in a row, but then the top one disappeared! (the place it was in is circled in red)
and if u had to see the battles-


but of course, he only got those 4, not including the one which went AWOL, after he and his full stack full of green troops was ambushed and alomst massacred by some of those Sweboz elite axe guys (only a half stack! ) halfway through the battle, when all was lost (my only experienced units were caught early on and massacred) my general sounded the retreat, but only a few guys made it out, including himself. anyhow, heres the battle:


my general from that battle pursued that enemy general with an army from greece which was very experienced and that was the army which won those 5 famous battles.

anyhow, the question i wanted to ask was why did that famous battle marker go AWOL?!?!
