Figured it out. DynDoLods's texture mismatch errors were right all along... Seems Water Effects Brightness and Reflection Fix and Water for ENB in combo are simply a no-go when using DynDoLod. Maybe because Water Effects includes DynDoLod Lods but doesn't update the matching vanilla lods like Water for ENB does. So maybe it would work until you run DynDoLod again and get a mismatch, or letting it's lods overwrite DynDoLod's output? Disabling Water Effects Brightness and Reflection Fix solved it though.
