Steps to reproduce:

1. Sleep on a bed in TF dimension as it is raining

What I expected to happen:

It doesn't

Issue related to Mojang being Mojang; see my write-up here

I remember looking into this with another dimension mod.
DerivedWorldInfo is to blame and is the default WorldInfo instance for all non-overworld dimensions.
