Custom Weather Transitions in Essentials v18.1

[gandapp]

I want to make a random weather system and keep the same weather on all the maps in the overworld. I commented out the weather clear that is in 'PFField_Field' (just search for the keyword: 'weather'). So this should stop the weather from changing between maps. However this only partially works as when I transition between some maps it looks like the weather overlaps ? Or at least the weather seems to shortly become darker ? Maybe the animation restarts ? I do not know exactly. Does anyone know if there are other scripts that handle the transition between maps. I would like the weather animation to be continues like it is if both maps have the same metadata.

In the attachements I included an example, as you can see when transitioning the screen gets darker and then goes back to normal.
