I was looking through conflict losers in FNVEdit and came across something I thought was odd. TTWFixes sets XCLW - Water Height to 0 for quite a few cells while the base game and nearly every other mod I've come across sets it to -2147483648.000000.
So if you have a large load order, most if not all of those records from TTWFixes will get reverted but if you are running just TTW by itself you could end up with quite a few cells with what I assume is the wrong water height value. When I ran across this in Skyrim, the effect was that as you'd hit a certain elevation, visuals would act as if you were under water even though you weren't.
