That sounds fair, but my biggest problem is there's still no promises that fairies can cast their "Cure/Apply Ailment" spells if we do that, currently Player Fairies are forbidden from casting spells effecting others luck/balance when those settings are disable (which I guess makes sense but I still feel robbed because Sims don't just randomly turn my PCs into Vampires either, and I can keep that, but not simple stuff like Ailments :/)
In Any Case, the real problem on my end is the contagious spread...any time you get proximity driven programmatic spread timers bad things happen in programming. And the more complex you make the math, the more unwieldly it becomes to debug/fact check.
What a computer can never fully simulate is the effect of immunity...and I'm not even talking retroactive immunity....some people just don't get sick in the real world, no matter the illness they come upon, a machine can't calculate that. As a result any attempt to spread contagiously as a calculation becomes flawed when processed by a machine because it is missing a key variable in the equation. Funnily Enough the "Immunosuperior" people constitute a larger portion of the population than most people realize...the amount of people exposed to a specific illness that will be asymptomatic or fully immune can be as high as 66% of the population, depending on the virus. The Computer basically by comparison calculates every disease as if it were cancer.
