2000+ movepoints heroes after their death or deleting

I tested it in the game. If a hero stands on a watering hole, you remove it, and then dig it up again, they will have 3000 movement points. Moreover, if you move them around, remove it again, and dig it up, they will still have 3000 movement points.

Visiting a watering hole that grants +400 movement points before removal does not grant starting movement points when the dug-up hero is recovered.
