No need for the big font. Anyway it has never been tried, but we can't make it where if you get bit once you need to take it. Taking zombrex doseages in the main game as set time missions in the missions.txt. So you'd need to figure out which coding is doing what and apply it to the Sandbox time that is used. A lot of effort for a little thing if I am personally honest and it seems kind of useless in sandbox where they take that out so you can enjoy yourself.
