Select Tools BUG at 4.4.1.0

[bukopu]

There is two BUG:
One is,I select a place,I type "/res select size",it display the right place.
But when I continue to select another place.It still display the first place i select.
This bug only with select place with select tools.Use "/res select [x] [y] [z]" haven't this problem.

The other one is,when i give a player op permission and remove his op permission after serval minuts,he still can distroy the other residence block.Even he relogin,he still can distroy the other residence block or use the chest which in other residence.

Hope you can fix it.Thanks
