Changelog History

in short:

• Advanced diseases now have a random cure generated.
• Advanced diseases no longer present their details by default and need to be analyzed first.
• Advanced diseases change their strain when mutating, which makes them unknown again.
• Advanced diseases can mutate spontaneously while in a host
• Some symptoms can now be treated using reagents. These symptoms stop acting so long as their treating reagents are in the blood stream, and they symptoms that can be treated are limited to those that couldn't be treated otherwise. The treating reagents are removed at an accelerated rate
• Advanced diseases spawned by events gain bonus stats depending on the event's severity.
• Disease outbreak can now be a major event
• Admins can now create their own custom disease when doing an admin disease outbreak event, allowing for direct stat boosts as well as trait selection
• The antibodies metabolism traits has been removed
• Virology gets new chems to help them modify diseases without needing to reanalyze them and to prevent healing viruses from mutating

Why It's Good For The Game

Diseases are currently trivial to deal with, to the point where you don't need a virologist at all except in some very few edge cases where a disease has the correct symptom combination to allow it to be stealthy(which usually makes it very benign or makes it cure itself).
In addition, the majority of threats and challenges, specifically the severe ones, the station has to deal with throughout the shift are either combat based(blob, xenos, terrors, morph, demons, etc) or things mostly beyond the station's control, where fixing the damage caused is the only recourse(meteors, APC short, etc).
This PR aims to make diseases more than just a mild inconvenience that is cured by clicking someone with a health analyzer and sending a message on comms and more of a challenge in it's own right that the station in general, and the virologist specifically will have to face.

Changelog

🆑
add: Stabilizing agar - prevents disease from randomly mutating
add: Tracking agar - Makes new strains created from the tracked diseases to be analyzed instantly provided the first tracked
strain is known
add: Viral Genetic Material - Produced by injecting black slime cores with blood. Counts as 2 stages for the purposes of finding the cure
del: anti bodies metabolism symptom removed
tweak: Advanced diseases now need to be analyzed to display data
tweak: Stealth diseases now show up on scanners after being put into the pandemic
tweak: Advanced diseases now randomly generate cures
tweak: Advanced diseases can now spontaneously evolve when infecting a new host
tweak: Disease outbreak can now a be a major events and gives the disease random bonus stats depending on severity
tweak: Some symptoms can now be treated using reagents(full list on the hackmd document), which removes those reagents at an accelerated rate.
tweak: Excludes longevity from the symptom list of disease events
tweak: food and containers are now contaminated when transferring fluids to and from sick people/bitten and when they are filled with contaminated blood.
fix: Sets the correct flag to null on normal huds so they no longer behave as goggles for the purpose of eye protection
fix: Data now gets properly transferred in chemical reactions

Can't find the proper way to mark an issue, but shipping viruses cause the virology goals to change.

I didn't touch anything to do with viro goals directly, though from looking at the code it does seem intended. If all your goals are complete you roll new ones.
