Weird Affliction

[Endoperez]

I've seen it happen occassionally, but it's quite rare.

Also, I think sieges, and especially moving forces to break siege, moving sieging force away from the castle or reinforcements to the castled province and/or breaking siege might cause weird effects. The order of movement is affected by ownership of the provinces in question, and the province under siege isn't owned by the besieger but the besieged...
