### Round ID

31996

### Description of the bug

Rolling observer gives you "ghosted too recently" cooldown

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

I should be able to start playing facehugger right away if I didn't play this round.

### How do we reproduce this bug?

1. Join as observer because there is no available xeno
2. Try to click egg to join as hugger
3. Be hit with ghosted too recently message
...

### Issue Bingo

- [x] Issue could be reproduced at least once
- [x] Issue happened in a recent (less than 7 days ago) round
- [x] Couldn't find an existing issue about this (https://github.com/cmss13-devs/cmss13/issues)

Reproduce the issue using the listed observer-to-facehugger steps, preferably against round 31996 or an equivalent round. Trace the cooldown check reached when clicking the egg and verify that observing without playing does not block immediate facehugger joining.
