so are we! We are going to replace the sheathing and possibly some of the trusses, and the end caps. Thank you for the blog recommendation.
The first point I wanted to add was that mold is a fungus, and when a porous substance that has been infiltrated with mold mycelium, like a shiitake log, it will always flush mold patches under the right atmospheric conditions, no matter how fleeting. So unless you can keep the bathroom super dry, by never showering or bathing and running a dehumidifier on cloudy days, it will keep coming back.
The second point was already made, but rarely do walls grow mold without a leak in the wall. It's more common in high humidity regions in areas of the home with low circulation, like behind a bookcase, but in dryer temperate zones it is usually a leak.
