I have used the Searchfunction with "resin hole" and "resinhole" and didn't found something similar.
On SMP, if another player extracts a resinhole, it will get shown as would nothing happened to it (resinhole still full). And even after disconnect and reconnect it was still full (only Clientside) even if the other player is seeing that it's empty.
If i harvest resinholes myself, anything will get shown as normally in SSP.
I just wanted to say that, because it makes COOP with a Rubbertreefarm a little bit annoying.
