I'd like to know how anyone is getting custom hairs to load. I put them in and bam! Game will not load even after letting it go for a few hours to the main menu.
I managed to get my custom hairs to work now.
I moved all my mods to the WA folder and deleted all my cache files. That was all I did. I now have numerous hairs, eyebrows and default replacement beards and stubble. All working how they did before.
I can only assume it was because they were in the wrong place despite my other mods working in the vanilla folder. So if you haven't already, try that.
I don't have any hacks installed yet. Just Delphy's breast and Jonha's sliders, clothes, default eyes and skins and the hairs.
