Backports from the 1.21 version:

• groundcover_cannot_generate_on tag and groundcover generation improvements (e.g. try to not place twigs in villager houses)
• harvests_mossy_hollow_logs tag + mossy hollow log improvements to moss placement and harvesting
• The other 1.21 features will be backported in a future update

Also, I have a new wiki! https://orderedchaos.dev/mods/minecraft/project-vibrant-journeys
