Thanks for the support!
Funny enough it crashed even HDT-SMP, True Directional Movement, Skyrim Souls and Better Third Person Selection all disabled.
I'm starting to suspect this is related to memory issues (even though I'm reaching 80% memory usage, but I am on a gaming laptop) or DynDOLOD. Hmmm
In many cases, I'm able to outrun the LOD in heavy areas like Whiterun. When I arrive, the area will be grassless and without people. Then after about a minute they pop in.
