Very strange Casse bug

[Malik of Sindh]

Its 267 BC.A welsh rebel(Cymriu) army stands near the province north west of Camulosadae.I though I will test how this guerilla warfare works and send two generals to attack that army.When I entered the battle all I could see was sky and a bit of battle map,but it looked like I was below it.Also my king Baraes bodyguard was somehow depleted to 18,even though he had 54.This happens only in this province.No crash,no nothing.I don't have pics,ad I can't remeber the province name..I can take a screenshot if needed.
