1) Three "Great Fiend Spider" dude/dudettes came over as the guises of 2 x Maceman & 1 x Baroness Concert. They were guests due to my well known Inn. However, all the decided to do was go around bashing in doors - even after arresting them, & beating them up. Going to appoint a Hammerer now...
Ergo: As guests, disable Building Destroyer?
2) Animals with fire properties being sold. Several times now, either a Jotun or Elf caravans decided to bring such exotic animals, they couldn't even keep them under control. Specifically, animals with "feet of fire" or other fire based properties. They lead this crazed animal, either inside the caravan or behind one pleb, whilst it spews fire angrily to no avail. The moment it enters the Trade Depot, however, it burns everything at the Depot, kills pretty much everyone nearby, then makes a run for it with the other animals.
Ergo: Wax cages?
