I've extracted the key information from your text:

It seems that you're having issues with a plague doctor skin not showing up in Back 4 Blood despite subscribing to it. According to the provided instructions, the issue might be caused by another plague doctor skin having the same name. To resolve this, you can change the mod's name by locating it in the `steamapps/workshop/content/2620601541268940` directory.

Additionally, I'd like to provide some general information about plague doctors and their role during the Black Death pandemic. Plague doctors were tasked with treating victims of the disease, which was characterized by its high mortality rate, wiping out approximately 25 million Europeans in a short span of time. In desperation, cities hired a new breed of physician who wore all-leather suits and beak-like masks to avoid contracting the disease.

If you'd like to change the outfits or skins for your Cleaners in Back 4 Blood, you can do so by opening your Hub menu, navigating to the Cleaners tab, selecting the character you want to modify, and choosing a new skin from the available options.
