they SEVERELY overspawn, like, hundreds at a single beacon structure
also, when one of them got hit by an archer, they killed it and then aggroed on me, as if i had hit them.

Thanks for your report!
Could you provide screenshots, and ways to reproduce the overspawn issue?
The aggro issue is a known issue.

o have no clue on how to reproduce it, but here are the screenshots (note that i've already killed a lot of them)

(also, nice temple, man)

I was able to reproduce it after a while. I will look into it :)
