I sent a small invasion force to gain a foothold in the southern Hispania/Privateer region, they both have an alliance. I conquered some settlements along the coast in preparation for my main invasion force which will come later but they retook 2 settlements from me and Plague has been constant, will it ever end? Is there anything I can do to make sure Plague doesn't come? Building buildings that improve health but is there anything else I can do?
This Plague is effecting every single settlement that I conquered along the coastline.
