NPCs being infected when zombies are turned off?

[Professor Paul1290]

I'm not sure whether this is intended behavior or not, but we've had at least one case where an NPC was infected even though zombies were turned off.

We haven't been able to re-create it intentionally though, only that one case with one NPC.

Do infections carry across areas?
If they do then perhaps it might have been carried over from a previous area where zombies were turned on.

Yes, infections carry across areas.
