To reduce the load on the main thread and to produce nearly instant results, all operations within CPlot that modify blocks are done in other threads.
After such an operation finished, the changed chunks are synchronised again with the world on the main thread and should be updated for all nearby players.
However, it not only appeared to me but also to one other person that changed chunks are apparently not sent to other players, forcing them to reconnect to see the updated chunks.
But I was never able to reproduce this problem on a clean server, so I can't rule out that this is a not problem with another plugin.
