[0.915] Monsters are still not attacking the AI
Unfortunately, it appears that the AI is still able to found cities near monsters and can release them if it plants an outpost near a monster lair.
I was playing as Resoln and I declared war on the Altar faction (they were close... and weak...). When I took their first city (forget the name, sorry. It should be the city on the far east end of my empire in the save) I noticed that a ravenous spider army (and nest) was directly southeast of their city. The game save I have uploaded below is the aftermath of me taking the city and noticing the spider lair.

I continued playing and I noticed that the Altar outpost directly northwest of the town I had just taken had just released a hoarder spider army. Unfortunately, the spider army did not attack the outpost, and instead started wandering aimlessly in the woods just north of my newly conquested town.
One more unrelated bug to report: if the Resoln faction loses an elemental that spawns from a node, are they capable of training a new one from that node? In the game save that I have uploaded, I lost a death node demon and could not replace it. Nor could I replace a crow demon from my air node.
