Ideas
I don't understand in any way, this statement of yours.
First of all, "disabling the rain" is an option that simply does not exist in the reality of the game, you can disable the weather effects on your sims, but it has no relevance to the problem we are examining.
Secondly, then, furiously complaining about solving this bug is more than legitimate for all those who like me spent 40 euros just to have rain and snow. And if the only thing that this EP was supposed to do it does not do, it is normal to expect that customers are furious and ask to put the problem as a priority in the agenda of EA developers who are dedicated to solving bugs.
There is no other marketing like that of "The Sims" where thousands of people solve for free with mods what other sell; in all other marketing they would have already failed, forgotten, buried.
So if you want to help, collaborate on the solution or take care of the bugs that you consider a priority.
Disabling rain is literally an option in the game menu.
And I did help and collaborate- I provided several comments with additional insight on the problem. Which is dramatically more than "fix this bug!" does.
