Got a very strange one here.
Opened up MO2 today having run DYNDOLOD yesterday with no problems and thought I'd try adding in the Noble Skyrim Billboards. Basically things did not go according to plan so I just uninstalled the NS Billboard Mod and re-ran DYNDOLOD.
Now EVERY time I run it the programme freezes (not responding) whenever it gets to:
textures\terrain\lodgen\skyrim.esm\tundradriftwood01_000b8f53_n.dds normal map not found, using flat replacment
