1)Simply disable mods one by one and go into game to see if it helps to find which mod causes problem.(Or disable last half mod;line them in date order and try or you can specificly target a mod if you remember when this problem started.) 2)Be sure you are not using any Oldrim mods for SSE.Also be sure all plugins are enabled in Vortex plugin menu. 3)Disable everything and go into game like that. 4)Think if you downloaded any mod that alters that areas. 5)Go nexus vortex help.Read some guide. 6)Simply dont download mods without reading comment section,%90 someone encountered same problem or conflict between mods and talking about it.Especially if its a building or space altering mod.

1)Dont use NMM,simply outdated;only crazy people still use it. 2)Brown face is generally because of load order problems.I dont know how NMM works and handles things;i have never used it. it happened to me once when i had messed up load order and installation order.(Change your load order/installation order to solve problem) 3)I can bet my worthless life that there are some conflicts between those mods. Look at them in Edit and either dont use some of them or create patches.(look at edit to solve conflict) 4)After doing everything,realize even in normal Bijin scenario,there are still neckseams.(Download Bijin compatible skin and body textures) 5)After downloading realize there is still tiny neckseam.When it sometimes becomes unbearable or fine,completely depending on your ENB/light/weather/etc(Learn to live with it or texblend).
