[Gate-users] warning

[王振天]

when run a .mac, there are many warning messages like this:
"world_L is registered to the default region.
  Volume of the same name and copy number ("world_P", copy 0) still exists
and is being used.
  Be warned that this does not necessarily guarantee it's the same
  volume you originally specified in /vis/scene/add/.
/vis/scene/notifyHandlers scene-0"

is this harmful? and what's the problem?
looking forward to your help,thank you!
