Hi, Hope this message finds you well. So I was playing on the latest snapshot and I noticed a couple of bugs hope that they can be fixed.
Bug 1: Raining inside a building/closed roof
While I was playing I noticed that when it rains the rain particles are still seen under a roofed area as shown in the Screenshots.
Bug 2: Saplings not growing
I also noticed that the quadruple saplings (Large spruce trees,Jungle,Dark oak) saplings are not growing whatsoever altho that the tick speed is set to normal as shown in the screenshot.
Only 1 bug per report please.
But as for the two bugs you've reported,
the first has already been reported, and the second can be fixed by optimizing your world. They can both be fixed by optimizing I've found.Rain > MC-179845 Trees > MC-179909
