But not sure if it works for Mined by too. But also, hidden drills probably shouldn't show up there and this could be a bug

Thank you, seems like a short list but will note for the future

You can make flamethrower turrets heal biters instead of damaging them . Technically also not a nerf since they'll be able to heal buildings if they're near biters
