Issue Description:

I think it's a legitimate bug. Very handy for making an elytra runway, but still a bug.

What happens:

Under specific circumstances (when hitting a low ceiling while holding [Space]) Living Armour augmented with Elytra "sinks" into the ground, the player's feet are anchored to the floor.

When paired with Sigil of Haste, the player can slide across the floor at incredibly high speeds.

The trick works only on flat surfaces, any bump will stop the slide.

What you expected to happen:

I would expect the avatar to immediately stand up and not do this. I mean I'm glad that it works because it's hilarious, but not exactly the most balanced thing in the world

Steps to reproduce:

(see attached file for live demonstration if the upload works)

1. Wear a full set of Living Armour with Elytra augment
2. Stand right under any solid block
   2.5 Activate Sigil of Haste (required for slide)
3. Jump and hold spacebar for a moment longer, but release before it hits the ground
   3.5 Look down, below the horizon line
4. Press "W" for superslide. Spacebar+look up to fly upwards. Look up without spacebar to stand up

Affected Versions (Do not use "latest"):

• BloodMagic: 1.9.4-2.1.0-68
• Minecraft: 1.10.2
• Forge: 12.18.2.2171

This is a general bug with the Elytra upgrade.

Possibly something that indicates that Forge needs fixing first.
