Make it so their ai tries to go west more or so the khazars try to push them out

Indeed... I will revert the change.

sri lanka wasnt actually an island until the tsunami a few years ago funnily enough.

The main point of the Reasonable mod collection is to improve megacampaigns starting from Early Middle Ages (769). From my experience, the Magyars only sometimes expand West, and the passage to the Pannonian basin should help them in such cases.

Does this only work in year 867 or is the AI also competent enough when you start in Charlagme?
