HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

A couple of times while playing on WT+HD, I encountered incorrect functioning of the guild rebuilding feature. For example, here I couldn't rebuild the Blindness structure in Inferno: http://zalil.ru/29919395
I would like to know if this is a bug in WT or if it is related to the mod's operation.
