One invasion of Ilkhanate stuck for 10 years!

[unmerged(457435)]

just like in the title.

The situation is this: Ilkhanate is invading one-county state and its invasion is stuck on 59% for years. just because this ruler has extra-county vassals in Cuman territory and Ilhkhanate is not going there! I can provide a save if needed.

Nevermind, it has already been resolved by itself.
Golden horde arrived, declared war first on cumans (and won it) and then on that county too. When golden horde invaded those extra-county holdings, the war ended with 100% for ilkhanate.

But still... the Ilkhaate invasion of that one county lasted nearly 15 years...

Happened to me with Ilkhanate attacking Jerusalem, or rather Jerusalem ruled by Byzantine, when most was ruled by me. The war only ended because I supported Byzantine went round the back and sieged their back provinces.

For some reason the doomstack did not attack me. Still in both cases changes need to be made, both I and Byzantine had more men than Illkhanate, but could never win a battle due to the attrition.
