Shooting an arrow at full power into soul sand makes the arrow not stick to the block. Shooting it at a slower speed gets them closer but the arrows still don't stick.

hitbox bug, also noticed you cant go from a soulsand block into a 2x1 tunnel made out of netherrack or anything that is a full block
That has been in the game for a long time.
I'm thinking it's just a visual glitch now. If you walk by the block you pick up the arrow.

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
This is no longer an issue but an arrow shot into soul sand 1 block above the ground with just not stick and fall down.
Can confirm.
