When you paste blocks with physics, specifically sand, gravel, concrete powder etc. they do not always paste correctly. Sometimes it works flawlessly, other times some blocks will appear missing to the client (relogging or switching worlds fixes those).
Other times the blocks are actually missing. I suspect this only happens whenever there are many jobs going on at once (not in the same region, but on the server).
