Hello,
the way plugin handles tree grow up ticks, where it ent.kill tree and spawn bigger tree, it seems it confuses tree spawner. It seems like every time Nature upgrade game-spawned tree, game will register it as cut-down tree and spawn new one, so I ended up with thousands of trees on my server after 3 days, with grawUp tick rate set at 4 hours.
I increased it to 24h for performance reasons. While it is not neccessairly bug, because nature tend to spread, it would be useful to have option to respect vanilla spawner or apply grow up only to planted trees.
Thanks,
M
