NID 37061, I have already reported this issue on the original mod's page, but I'm not sure if it's appropriate to mention it here as well. However, just to be safe, I wanted to bring it up.
ENB Water ver 2.07: When selecting CS ENB Water, TexGen throws an error while generating cache: *"textures/effects/fxwatertile06_n.dds"*. This issue does not occur when selecting non-CS Water.
The latest version of ENB Water has fixed this issue, according to the author.
