When certain blocks such as crops or furnaces get out of simulation distance this mod will keep track of that so once the blocks get in again the mod will apply the changes it would have gotten if it never left the simulation distance.
This might have been fixed already but when playing in 1.20.4 on a server, started in a Mangrove biome and I believe it would try to simulate the propagule hanging from the the Mangrove trees. From there it would successfully grow the tree, creating more propagule causing the biome to over grow after coming back to the loaded chunks after a few times.
I was able to make a patched version which I believe either ignored propagule or did a block below check as well.
