While players no longer jitter on top of vehicles, they can get stuck in the same jitter issue by walking into the sides.

Condensing this bug into #83 for clarity on ground system issues.

I have also experienced this.

I have video of this too if you want it. From the same session as my video on the wonky plane crash stuff.

I'll take it for data, but it may take a bit to fin the source of this bug. Minecraft collisions are wonky.
