With the exception of the mud disappearing, I dont think they're game bugs because they dont happen when playing without ENB. It's only when ENB is on that it happens.
In particular when the following line is set to true in enbseries.ini it will show these defects
[EFFECT]
EnableAmbientOcclusion=true
if I set that line to false then they go away (and ENB is still running). See the following screenshots...
Hair without boxes

http://oi59.tinypic.com/1zyd3q1.jpgI added the following line to enblocal.ini as well based on someone else's recommendation, but it didnt seem to do anything. Definitely didnt fix the hair problem.
[FIX]
FixSsaoHairTransparency=true
If there's no way to fix this through ENB or ini settings, does anyone know of a workaround I can use (eg. doing something with the textures?)
As for the mud disappearing, that may indeed be a game bug because it seems to happen both when ENB is on and off.
