If that is how they INTENDED the tunnels to be, why make them at all? Not saying you're wrong cuz I have no idea what the devs intent was. It is just so horribly inaccurate. Like it shows in the screenshots I added in the report, those tunnels are literally designed (IRL) to be a form of air conditioning. I live in Arizona (usa) and it regularly gets to those temperatures here in the summer. There are natural underground caves here in the middle of the desert with flowing water in them that create such icy cold air that you actually get chilly just sitting by the entrance to the cave. Even in 115°f weather. I know you're agreeing with me, I just wanted to further my point of the report.
