We'll take a look I haven't removed them completely, although they only exist as an actor object now, which isn't much use for defending. If I create entities for them, what should they be called? Do you want the low wall as a separate entity, which has to be destroyed first before the Broch entity can be attacked with non-ranged objects? Edit: I fixed the majority of demo map errors. I'll let Mythos look at the 'We are Legion' map first as it needs unit replacements
