Hafiz has the same starting stats as in the vanilla version – the attack skill mentioned in the xls file is missing.
Dugald doesn't have the flag on the map in his hands. Also, it's not possible to transfer items from one hero to another every turn; for example, I click on Dugald twice with Robert, but only movement points are deducted from me, and this continues throughout the turn, but on the next turn, everything is normal.

update: The bug where heroes sometimes can't meet isn't limited to Dugald.
