As amazing this mod is, it is nowhere near as amazing as the dedication of his author, taking the time to respond to each and every idiotic reviews, from blackmailing to complains on things that are not part of the mod, not even made by him. And for that, top of my hat to you, sir.
And yes, using CSP and Sol since wut, forever, everyday as a basic nearly makes you forget that it wasn't part of the game at first, it is all made by some dudes, probably at home, for free. I love modding. Thank you forever, Peter!
To avoid this error, please deactivate the extented weather functions in CM's Drive settings, like it is described in the install guide on page 18! This are functions which were important for older weather mods like gbwSuite. But now they are obsolete.
