Try to copy light load order and run game through skse_loader.exe (dont run through launcher, it messes up load order)
I tried it with the light load order, still CTD. And I've always been using the skse_loader.exe
I'll see if I can measure the game memory usage and temperature.
EDIT: Memory seems fine, but my GPU temperature seems to get to 93 degrees, when I get the chance to clean it, I'll retry.
EDIT 2: I've cleaned my side fans of dust, and haven't had any CTD's anymore. So problem solved
I do want to point out that the cave in hilltop house, whenever I enter it I get a CTD, might be an item there that gives an error.
EDIT 3: The CTD in the hilltop cavern seems to happen because of the stone mortar. If you go down the stairs and look to the right, on the rock is a stone mortar and pestle. I removed it with console and the CTD stoppen happening. You might have to look into it yourself.
BESIDES ALL THAT: Thanks for the amazing and easy to use modpack, I'm actually able to play the game instead of modding it into oblivion!
