Runners being too big in the tunnels?

[Mattmaster77]

Bug Description: Whenever a runner attempts to go down a tunnel, they are apparently too monstrous to fit. But when you evolve into a hunter, it's normal.
Here is the runner being too big for its actual size: https://gyazo.com/b22312e652e68490072e723573c2e9a3
Here is the hunter being normal: https://gyazo.com/0f0d11fe9fbd8c51564a8615dd7943dd

I am unsure if there was another report, but from what I searched up, there wasn't.

Steps to reproduce:
1. Observe and/or be spawned in as a larva.
2. Evolve into a runner.
3. Attempt to go down a tunnel.

Hmm, I'll take a look into that and add this to the priority buglist.

Bumping this up, it's a real problem.

Fixed!
