@PappaDavid worked for a singleplayer world or server world?

I loaded my world into single player and ran through the "Optimize World" option. I hopped into game and I was seeing correct values with the height map. I then took the world, (copy world folder as well as backup and unzip) to my server (locally and hosted) and when I loaded the same world into the server the issues persisted and what was fixed in singleplayer was broken again running on a server.

UPDATE:

I tried creating a new world on a locally hosted server and it too had incorrect height map values

Maybe I'm trying it in the wrong place but I downloaded my hosted world, (20w16a upgraded to 20w17a), tried to do an optimize world (with erase cache option) from the single player menu and the game crashes with

"The game crashed whilst mouseclicked event handler
Error: java.lang.NullPointerException: mouseClicked event handler"

I attached the crash report. Nothing stood out to me but it looks obfuscated

UPDATE:

I launched a server locally with the --forceUpgrade and --eraseCache args and I was able to bonemeal 2x2 trees.

I also found that I no longer had rain falling through my roof

UPDATE 2:
I found I still have some spots in my world where the height map is messed up.

I have this issue as well. I created a world with the previous snapshot fwiw.
