* Removes miasma and gibs diseases (#83455)
## About The Pull Request
Removes miasma generating random viruses (in two locations for some
reason)
Also removes diseases being generated by gibs, which is responsible for
a lot of disease spam
## Why It's Good For The Game
New diseases are spread through events and virology (and some other
minor sources). Miasma and gibs are a source of random viruses that
dilutes player response to diseases. It's frankly exhausting curing the
disease outbreak, just to see 10 others pop-up. Hopefully we can reduce
the madness a bit and place more focus on individual diseases
## Changelog
🆑
del: Miasma and gibs no longer generates random diseases
/🆑
Something like lung rot could be cool though, but out of scope for the
current PR
