My intention

I made this mod because i always felt that minecraft was lacking life, nothing seemed to change, when i cut down a forest, build a house, survive for a long time, its always the same. I always wished that things that i build can experience aging, like in real life, but without any new blocks that is not in minecraft, one of the mods that inspired me is the mod "Immersive Weathering", the feature i liked the most is the spontaneous growth of grass in fields, however i did not like the new blocks they added into the game, so i decided to code my own mod that does what i wish minecraft would look like, without any new blocks, structure will crumble down through time, forests/grass/plants will spread over time, and here it is...

Server lagging with Nature Is Alive – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Nature Is Alive consumes the most tick time.
