When te bamboo is generated naturaly it collapses and fall to the ground. Reducing the max heigth of bamboo dont affect and deactivating the garden module fixes it.

Hm, looks like somewhere is capturing the old bamboo state.

Encountered the same thing. Caused a massive lag spike when all of the bamboo items fell.
