i think i know what this is about.
I think, that the mod uses the new function that applies a force to a bodypart each # turns to make it seem like the gravity's holding tori down, and then make the gravity upwards. i have no idea why... but it could be that the tomahawks are to be heavy, but still dly straight.
to confirm, would someone more skillfull than me just remove one of your feet, or, if nothing happens, both of them, but not dm anything but the ankles?
