@Peter Rabbit can i get that datapack, updating the .json file for the Import Settings button is a lot of work and my most recent version got lost when i got a new laptop
thanks for offering your help Michael but i already have another computer to test the snapshots on
i think i can use another computer in the evening and continue updating this bug report.
also my computer is a lenovo T430 and only has intel HD graphics 3000 while the minimum requirements are intel HD graphics 4000
my current computer did not meet the minimum requirements and now snapshot 20w10a does no longer work for me and i will be unable to properly update the affected version on time
the bastalt deltas stop generating the ground above y127 so its just netherrack instead of blackstone or basalt
i got a file that is working again
the file i normaly use for the bug test is broken as of 20w49a
unfortunaly i can no longer test and update this bug report until i have a new file/datapack
the multiplayer sleep datapack from https://vanillatweaks.net/ sets the weather to rain for 1 second to reset the weather
seems to be fixed, but biomes seem to generate 2D and not 3D
