I tested to see if the previous collision bugs where fixed so I push up against a wall and fall down.
When pressing towards the wall from the start of the fall you end up slowly falling down not even taking fall damage. And if you move towards the block you fell from it will put you back on the block you fell off of.
How to reproduce:
1. Build a wall.
2. Put a block attached to the wall that isn't touching the top layer.
3. Stand on the block you just placed.
4. Walk off the edge as you are pressing towards the wall.
5. Also if you press move towards the block you fell from even after falling it will put you back on the block you fell from.
