Thought I'd check in...
It's interesting I havent been noticing beast activity much recently, seems to be getting less and less since having made the big plan-
ACE?
Anyhow of course we should not get complacent and be ready for beast attacks with the AVRT militia waiting in the wing but it's definitely noticeably less recently.
I'm thinking though its like if your enemy knew you were heavily fortified they wouldn't bother attacking after a while.
