One line summary of your issue
Councillors keep dying of Great Pox - 3.0.1.1

Game Version
3.0.1.1

What expansions do you have installed?

The Republic

Do you have mods enabled?
Yes

Please explain your issue is in as much detail as possible.
Note:
I am not able to turn off the mods as that would corrupt the save, as many characters have traits which would cause it to crash if loaded outside of a save.

Alright. So, basically, my councillors keep dying of the great pox, for no particular reason at all. It is them and only them that get it in my court. Not me, not anyone else. None of them are homosexual and they are all male. They are all unmarried and even the celibate ones keep getting it. Please help.

Steps to reproduce the issue.
Hire councillors. Wait.

Note: I don't actually have the Republic. I just forced me to pick an expansion or else it wouldn't let me report it.
