A few 1.21.1 bugs

[Meiseside]

The loading of lava and water with the tanks is buggy. I place the liquid in mid air AND filling up the weapon.
Also the players' arm model is locked facing north in first person when shaders are enabled. And the revolver has no animation at all.

Yeah, same with the revolver. So cool mod, I hope it will be fixed soon
