Mongols stuck in never ending wars against enemies with unconnected territories

[Ephafn]

In my game, the Ilkhanate has been doing nothing for the last ~30 years or so. It is at war with some random muslim duchy, but it has only conquered the province next the Ilkhanate territory, leaving the farther (unconnected) provinces untouched. All of the 200k Mongol troops are sitting there too. As the warscore is only 21% (after sitting at 17% for a very long time), I don't think this war will ever end. I reloaded twice since I spotted this issue, to no avail.

Also, in the same game, the Golden Horde seems to be in the same situation. It attacked Ruthenia, which is split in the middle by Rus. It has full control of the Eastern part, while the Western part remains untouched. Strangely, they haven't attacked Rus, which have joined the war on Ruthenia side. This war will probably end at some point, since the warscore is at 94% right now.

Is it so that Mongols will not go into neutral territory?

No, the problem is that the AI doesn't understand how to find enemy holdings.

This has been a problem forever.

I had a game where a single count revolted, and had held a few random baronies in counties that weren't his. All his AI liege did was sit 50k troops on the county 20 years. Never went after the baronies.

Thanks, I wasn't aware the bug wasn't specific to Mongols.

I guess that bug made my game much easier, since the Golden Horde now have joined the Ilkhanate war (still only at ~30%), and I'm its neighbor.
