ToME: the Tales of Maj'Eyal

I entered my home through the portal to it outside, to upgrade my rod of recall. When I tried exiting the fortress after upgrading the rod, neither of the exit portals would work anymore. When I stepped on them and pressed either < or >, nothing happened. The rod of recall obviously didn't do anything either, since I was already in the fortress.

Saving and exiting, and restarting Tome fixed it.
