As the title states, I was building a new base in the North of the Exiled Lands. When it started raining, as it does quite frequently, rain was coming through the glass sections of my new base. The solid roof pieces and solid wall pieces blocked the rain, but neither the glass roof or glass wall pieces seemed to stop the rain.
Whatever feature was added to stop Stormglass walls and roof from allowing rain to penetrate, please copy and paste that code into the other Stormglass pieces, too. (No, I don’t know coding, as you can probably tell from my suggested solution.) Hope that bug report helps.
Some one made a lengthy explanation of why rain goes through the glass pieces. I have not built with it in a rainy area. I believe it has to do with light coming through allows rain also. @Bodin
