Changes include:

• Mask filtering is now entirely separate from a mask's condition. The air will no longer act like acid, so your masks & headgear will still remain intact physically but won't protect you from the virus if their filters drain!
  
  
• Medical mask boxes have been added. Pharmacies & medical areas will have medical mask boxes that will contain invaluable medical masks.
  
  
• Cloth masks are now their own item. Now you can equip them with ease, unlike vanilla bandana face masks.
  
  
• Susceptible trait cost changed from +7 points to +11 points.
