Anyone experiencing missing rain effect bug?

[FoxtrotOscarEcho]

I don't know what causing this bug, but...

!!! SPOILER !!!
if I go to the rooftop of the abandoned building with the BR easter egg near Metro: Congress & MLK
!!! SPOILER !!!

leaving the place and fast travel to somewhere else, the rain drops stay there. When I reload the game I hear the raining soundeffect and see the wet texture effects on the roads/walls but the falling rain drops are missing. I'm using the Climate change-rain mod for testing it.

It's a bug or the problem is on my side?

I almost never see rain in my game except thru V's Apartment window.

Then I run out my front door to see the rain and there is none!
