How does respawn work?
Here's my wondering: how do machines fill sites you just cleared out so quickly?
I have a theory: there are tunnel networks connecting cauldrons and sites, so that when machines have been taken down, or when machines have been overridden, they can be replaced from the machines transferred through the tunnels. Why don't we see the transfers ourselves while we're still there? Because it can't do it while there are humans watching. Although, this is only a theory. I was only trying to make sense of the moments I leave a cleared site's border's just slightly, immediately coming back to machines that seemed to have come from nowhere, and a machine that I overrode missing entirely.
Let me know your thoughts and theories in the comments below.
