I believe the Weather ID decimal is 1113726 which would make it 0010FE7E (RiftenOvercastFog). If I force that weather, my fires go brrrrrr.... So that one doesn't seem to play nice with the Heavy ENB preset.

I played around a bit trying to find the mod responsible and in the end toggling the ENB Helper SE gave the hint to it being weather related. So it seems to be related to weather. If I just wait 24 hours for eventually another weather to kick in, fires are back to normal. So I guess it is maybe one specific weather situation that causes this, not sure if it's worth finding out which one (and how), so that it maybe can be fixed?

Here's a picture with the ENB turned off:

I have an issue with fire sources being very dim in the game. I run with Postprocessing and ENB (Heavy) installed and just double checked that I have all the Post-Processing affected mods installed with the ENB options. Also did another run of re-installing Embers XD to see if it fixes this, but it doesn't. If I turn off the ENB (Shift+F12), fire looks quite normal, but with ENB on it is very dim and doesn't cast much light. Screenshot is from the Windhelm entrance for reference. It affects fire spells as well. But torches seem to be less affected - at least I didn't notice anything unusual on torches, but playing a mage, I don't use them to run around... on the walls they looked ok'ish. Any ideas what I can check to find out what's going wrong here?

Yes, that seems to be it, thanks. Disabling the grass cache in the ini fixes the graphics and also the massive stuttering in Wyrmstooth. Guess it's either Grass Cache or new worldspaces, until there's an AE-usable way for grass-cache creation. Or maybe I should just downgrade to generate the additional files for the worldspace and then bring them back to the AE-installation... hm...

I tried adding Wyrmstooth to my Step 2.0 install and got weird graphic errors (see image). Narrowed it down to being caused by the Step Conflict Resolution Patch (with-grass edition), whenever I enable that, while it doesn't seem to specifically touch anything in Wyrmstooth, the graphics in the Wyrmstooth world go haywire. Trying to narrow it down further, but if anyone has any ideas... I know Wyrmstooth is not supported by Step, but maybe someone knows how Step is interfering with it to cause this.
