Mysterious horses

Ok, i just went and occupied a lvl 9 crop oasis with 852 cats, loosing 4 in the end. I went back to my city and found i had 21 horses(before the fight i had 9, which also mysteriously appeared a couple days ago, i trained no horses nor was i attacked)not saying its a bad bug getting free horse but i thought i might let you know

That's wierd

Ghost ponies!

If ur convince skill is high u might have captured em from an enemies traps

but he wasnt attacked...
