Do you mean that NPCs can actually destroy the base??
i don't know. Huor wanted to create another base plugin for the IC base and one of his intentions was, to make it destructable. but after we experienced heavy problems with the first attempts of the new plugin Huor said, that it is more complicated. this was a reason for us to use the established base plugin. but i don't kow if it is possible to change the settings of a specific base so that it is destructable. imo we should not risk our efforts with building the base in a danger zone.
