I did notice that on my last build, but it was the original sloped ones I guess. Just in one spot, I could see the rain. Somewhere I don’t normally stand, but do run past. At the time, the grass had clipped through the foundations again, so I wrote it off as associated with that.

I like to build in the jungle, using the Lemurian ruins, so it rains all the time. Good to know about this, thanks.
