Technical issues and problems with WoGa.

Good evening. I found a bug in WOG version 3.58f. For the Necropolis hero "Tant," the specialization is listed as "raising the dead" (when selecting the hero before the game), and it says so when you right-click on him, but when the game starts, the specialization somehow changes to something related to blessing, but the icon for the raising the dead spell remains. I thought it was a bug in this downloaded version, but no, it exists in all the versions I've downloaded and checked. Is this intentional, or is it actually a bug?
