After installing the latest version of this mod I once again have the issue that no matter the time set it's always night time in-game with g&b weathers (your modified original kunos and other weather presets are not affected). Tried it with different times, different g&b weathers, different Kunos and mod tracks, reinstalled good and bad weather suite manually several times (I recall one time I missed copying the script folder, which isn't the case this time), I copied over the files from fix03, and CM is up-to-date (0.8.1837.34607 (x86)). Should be unrelated but the shader mod is also on the latest version. I'm not using ReShade. And yes, I read the manual again, no idea what I am doing wrong.
Edit: With Laguna Seca it seems to work fine regardless of weather, with Imola, Barcelona, Paul Ricard (which I've tried so far) it doesn't. Does CM just ignore the time I set and use my local time (late evening right now)? I also noticed that Laguna Seca and 'Real conditions' sets it to my local time.
