Im not 100% sure if it is your mod. Didnt tested without yet.
Buildings placed by construction Drones and Blue Build for exemple, turns hostile to player.
Assembles are just annoying because u need to replace manually , but turrets are a real problem.
I can confirm this bug is from this mod, v1.2.0.
So far only Gun Turrets are converted to hostile structures if I place them with blueprints, while T1 and T2 assemblers, train tracks, belts, inserter arms, walls, gates, radar, and a few other buildings are not affected.
I tested with a chest and inserter if I could place ammo into the turret, and it worked. I was instantly blasted, and somehow the turret had a fire rate of base speed+45, lol.
