Well, hello there again!

Right after my previous tests with scaffolding I found something. Snow behavior is weird in 1 block tall crouch mode. Player model stands a little bit lower than expected. Compared to blocks and platforms same height, player on snow is y-axis lower than player on same platform. It causes some problems with slabs and stairs, which height is the same to 4 snow plates but you can crouch on snow and cant on slabs
