2.44 FOMOD installer has some issues and Vortex is unable to install it. The "DynDOLOD" directories under "02 Whiterun Exterior", "08 Solitude Exterior", and "05 Desync Birds of Prey" are mistakenly added as "file", such like:
<file source="02 Whiterun Exterior\DynDOLOD" destination="DynDOLOD" />
Not sure if it's the only issue.
