Staining on the OSB sheeting indicates there is a leak at the perimeter of this window.
This leak does not appear to be as progressed as the one at the MBR window, but over time will continue to increase as the materials break down. There was some slight microbial action in the floor system under this window.
After this leak is corrected the framing should be treated to eliminate any further microbial action.
