I have read several answers pointing out that this is not going to be done, the reason is that there are always complaints that there are people who do not like it. Same response for rain sync.
I accept that the synchronized rain should be optional, it is important but not a big problem if it is not.
But I do not accept that argument for something like this, this is a technical problem that causes accidents and wrong reports, and it is solved by synchronizing it. Removing options is not a solution, it is depriving users of new improvements and features from the original game. So you can not move forward, in the end the single player will offer a more immersive experience than the multiplayer.
It is your mod, if you have to make justified changes such as synchronization of random events you do them. It is not a cosmetic problem such as rain. There is no room for the likes of users.
