Loaded launcher on new Windows laptop. Go to launch new game and get the following error:

You’re trying to load a Bright Nights mod.
Bright Nights mod will rarely be compatible with DDA mods.
If you want to fix it, death\_function is now a list of spells, no longer hard-coded.

Hmmm, I am not loading that mod into the world I am using, are you saying because it is on the mod list in the launcher there is a conflict issue?
