/weahter command is broken. It changes the sky to look like its raining/snowing/thundering, but no rain or snow appears. it plays no rain sounds, either. all weather settings in options dont affect this.
images are dark; brighten if needed
Environment
overworld, superflat, "the void" preset
Seems to be fixed in 1.21.11 Pre-Release 2. I can’t recreate this.
