questions for the Haven developers.

Good afternoon, developers. I found a bug in WOG version 3.58f. The Necropolis hero "Tant," with the "raising the dead" specialization (as indicated when selecting the hero before the game), has this specialization displayed when right-clicking, but after starting the game, the specialization somehow changes to something related to blessing, although 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 versions I've downloaded and checked. Is this intentional, or is it actually a bug?
