On my server, when one places a grimwood sapling and applies bone meal, the tree becomes a set of ghost blocks for everyone in the area. This doesn't happen in singleplayer but happens consistently in multiplayer. This does not happen with other trees. Just ones from Atmospheric.

Closing as it is not marked as a bug.

Very considerate of you :D We don't mind putting the label there though, so no worries if it happens in the future.
