## Round ID
35732

## Description of the bug
(at least tutorial Abom) Loses the ability to walk after they use a lunge.
You can continue to lunge after the cooldown reset, but you can no longer walk.
Probably causing runtimes too, but I don't have logs.

Round ID: 35730

## What's the difference with what should have happened?
I expect using an ability doesn't permanently remove your legs.

## How do we reproduce this bug?
Become an Abomination.
Get a valid target, Human(preds and enemy xenos probably cause it too, but haven't bene there)
Use the Lunge
Try to walk

https://github.com/cmss13-devs/cmss13/pull/12737
Is probably the cause.

## Attached logs
```
N/A

Review PR #12737 first, then reproduce the Abomination Lunge sequence described for rounds 35730 and 35732. Done means an Abomination can walk after using Lunge and can still use Lunge again after its cooldown resets.
