does it exists a way to retrogen huts on a old world? some portals from the huts disappears and i can't make them reappear.

When a hut has been destroyed, it can be regenerated with the operator command "/regenHut". You need to be near the location where the hut is supposed to be to use this command.

That's all there is.

but when the hut already exists? it seems to doesn't work, but it's says that a hut was created. does i need to destroy the hut completely?
