Disease attrition broken

[ChronoTheTrigger]

Hi, new to the site so I'm not sure if this is the right place to post a problem report and help request. But I started a campaign as Saba, difficulty normal, on GC. Got all 3 parts of DEI mods, along with a music and movement mod, Dresden's all diplo mod, and No negative garrison mod. I've played with this combo of mods over several hundred hours so I'm sure they are not the problem. But the problem is there are certain regions such as Pura province across the Persian gulf where my armies are being completely annihilated by disease attrition. It is every turn, non stop, for dozens of turns! I'm taking like over 40 turns, it is an infinite amount of turns of my men dying from disease attrition. It has stopped my campaign completely bc I can't continue conquering the area and I'm at war with several factions in the area. Needless to say I got my ass kicked more than once trying to land invasion forces that are down to red units by the time they reach their destination.

It's impossible to play like this. Anything I need to do to change this? Sanitation is in the green and I've tried quarantining where no one moves in or out for dozens of turns and still, they getting wiped out by attrition.

Are you sure this isnt due to lack of supplies? Certain regions have harsh conditions where units will also take attrition if not placed on a road or city.
