Orcish Town raiding clan doesn't appear on other levels if Orcish Town is a bones floor.

[AndrioCelos]

It seems like the game doesn't recognise that Orcish Town is present if it is a bones floor, because the call to makelevel in mklev is skipped entirely. Because of this, if Orcish Town bones appear in a game, the exploring orcs, including the clan leader, will not appear.

I'm not sure whether this is intentional or not. Changing this will probably require explicitly storing the orc clan's name in bones files.

This is also related to bugs in variants such as TNNT that do other things with Orcish Town.
