Okay good so latest.

I feel like I remember there being a bug where air wouldn't show up but that was some versions ago...

I actually have another question, im currently doing a procedure that turns all air in 150 by 150 by 150 block radius to irradiated air because its for my nuclear bomb and im just doing player sent chat to start the procedure but when i start it it isnt centred from where im standing but instead, where im standing is one of the corners which is annoying because i want it to be centred where the procedure happens cus if a nuke goes off i dont want the crater to be the corner of the giant area of irradiated air, Heres my code below:
