ToME: the Tales of Maj'Eyal

I ended up having to kill t-engine while my character was in Gates of Morning. (Remotely, via kill command, if that matters.)

When I reloaded, it reverted to the save that happened upon entering the city. But since then, all of the buildings in the city do not allow me to enter them, including the hut with the portal guy. The people still trigger properly, just not the buildings.

I have tried saving and loading, I have tried exiting and reentering. I think my first-ever character that got this far is toast. Bummer.

Yes, I've encountered this one as well. The most common solution seems to be leaving the zone and deleting the zone's save file from the save folder. It should reset the zone. I don't know how it would affect quests, though.
