Pathogens contagious through glass walls.

[Erev]

Also, the pathogen reagent doesn't properly leave monkeys (and possibly players), meaning that if you get a new strain of pathogen you can't infect the monkey with the new strain, even if the previous infection died off.

This also leads to the 'reagent fart' symptom spreading additional 'pathogen' chemical until everyone's bodies are entirely full of 'pathogen' and no other chems can make it in. While it is fun to fill people's bodies with chemicals so that nothing else can be injected it'd probably be more fun if it worked as intended and filled people up with other chemicals besides 'pathogen'.
