Quirks don't save consistently

[ParadiseSS13-Bot]

What did you expect to happen?

Selected quirks to save properly and consistently.

What happened instead?

Occasionally, selected quirks will not save properly. This means that your selected quirks will (at seemingly random) reset when the round restarts.

Why is this bad/What are the consequences?

Selected quirks should save properly.

Steps to reproduce the issue:

Bug seems inconsistent; can't quite pin this process down.

1. Select quirks (I had spare points. Could be relevant?)
2. Wait for the round to restart.
3. Join the round.
