MMH5.5 - Heroes of Might and Magic 5.5

This is possible if a hero is sitting in the Castle.
With a normal teleport, the hero is transported to the castle gate.
With an advanced teleport (with a choice of a city and a mages guild of level 5), the hero is transferred to the castle itself.

Make sure the other hero is not blocking the indicated positions for each of the teleporters.

Thank you, kind person. We placed governors everywhere, and nothing worked.
