Lighting Problems with ELFX/Vivid

[Shabdez]

I´m playing with an ELFX/Vivid Weather combo and have chosen the darkest option for exteriors and the second darkest for interiors from the Vivid ingame setup.
The results of this setting match my expectations - at least most of the time. Two things are quite weired:

- If I get into a snowstorm at nighttime, the scene becomes extremely bright, even brighter than at daytime. It´s impossible to see anything.

- Sometimes at map changes after fasttraveling or switchting between indoors and outdoors, I can turn the lighting a lot brighter by simply equipping or unequipping an item or even by only Quicksaving.
When this happens outdoors, I would say the lighting BEFORE was correct, while indoors I think it is so AFTER the change.

Does anyone have an idea what causes this? Especially the second issue is something I would like to get rid of.

The load order of the two mods´ assets is as follows (LOOT):
ELFX
ELFX Exteriors
ELFX Enhancer
Vivid Weahter
ELFX No Breezehome
RAO-ELFX Patch

 

I have a bunch of other mods installed, but these shouldn´t interfere with lighting.
