Hahaha, dude you have air modes disabled. One or both of them. XDD Always make sure you have the Y button set to normal air mode, or most everything will effectively be broken. The modes are made for saves that don't require air, or where there is no option but to remove air function in order to make a save work.
I tried a simple MWAX/DESL/DEST bomb in all air modes. Knowing what it's made of, you'd think it would be pretty destructive. Wrong, it just made a small fireball. I have it set to normal air right now. I know this computer used to run TPT just fine (apart from lag). THDR on BRCK made almost no explosion, but it did crush some of the BRCK. Something is obviously wrong with the air pressure.
