you can do sword/shield surfing quite well in 0.0.81 - Not sure about 0.0.82 yet, 5hours makes me think you're saying it still exists

It's pretty easy to recreate (in 0.0.81, i haven't played enough of .82) just stick it between your knees, push it into the ground and draw it back towards you and you're sent catapulting across the map... Certainly one heck of an agility boost, I tell ya what.

Edit 1- Confirming in .82 that it still persists, if not, far easier to perform - even crates can do it now - and you can accidentally do insane physics sticking a polearm into a crate and lidding it "stuck" into the crate, affixing it solid and making it collide with doorframes and things, flung me /through/ (and stuck into) the ceiling halfway and I'm just like... "...why is my head suddenly shoved through a board...?"
