### Description of the bug

Somehow when becoming a zombie near the end of the zombie event, I didn't have any of the zombie-specific things, most importantly claws. This meant I could still pick up items, move bodies, interact with stuff I had equipped, and although I could not use guns, I could use tools and found out I was still able to turn on a welder and could start deconstructing a wall (did not go through with all the steps, if one was do-able all the others more than likely were too).

This bug is likely not reproducible.

### What's the difference with what should have happened?

That I should have claws or otherwise not be able to still (mostly) work like a normal human.

### How do we reproduce this bug?

I do not know how exactly it happened, so I will say what the circumstances were;
1) Was infected as a human, with more or less all slots except my active hands preoccupied
2) I was never killed between becoming infected and turning into a zombie
3) I was in a stasis bag at the time of turning
