Stop spiders from attacking other spider dens when spider dens are haunted.

[Kitty Cat Meow]

Example here:

 

 

 

Story time:

I once had a Webber base with around 12 spider dens, An idiotic ghost came around and simply haunted the nests and the entire place crumbled like a fortress of soggy tissue paper.

This amount of griefing potential shouldn't be in the hands of mere ghosts.

 

 

 

This is an annoying / potentially catastrophic method of griefing, It is the equivalent of the old "haunting stuff sets it on fire" mechanic to Webbers.
