Teleporting King!!!

[sharpshooter]

Like Macsen, I was chasing the HRE deliberately when he ended up in Friesland with no escape - only to have him reappear in Swabia.

This has happened a few times for me, notably with the Sicilian king, as mentioned.

Sometimes the AI just doesn't want you to have your way.

Its less extreme in the VI and modded versions of Med1. The most realistic explanation is that, since each turn is a full year, the crown prince would leave his current provience, with his bodyguard unit, by travelling to the nearest friendly or neutral harbor and boarding a civvy ship for the capitol provience of his domianions for his coronation. It would take the prince about twenty days to a full four months to get where he would want to go. It just looks wierd because of the game mechaniacs of Med1.

Ransoming is probably supposed to work the same way.
