UPDATE (Saturday Morning): This glitch has been fixed!
Following Thursday's site maintenance, here on Webkinz Insider we started getting reports from Topaz Terrier owners that they were getting locked out of certain rooms in their Webkinz houses, particularly bathrooms. Other Topaz Terrier owners were reporting that when they tried to place their pet's PSIs in rooms, they were getting blue boxes where the items should be. And, members adopting new Topaz Terriers were finding blank spaces in their docks where their gifts should be. Thank you to msbirdyskids21 and to Ergoiam for the pictures.
The reason for these problems is that the graphics for the Topaz Terrier Gift Box, Topaz Package Box (all pets with multi-item PSIs have two boxes, one is inside of the other), Topaz Sink, and Topaz Toilet are missing from Webkinz World. As soon as Ganz re-loads those images into the system, these glitchs should be fixed. In the mean-time, if you have a Topaz Gift on your account, you can still open it (just drag the empty space into your room). If you have a Topaz Sink or Toilet on your account, for now, do not place either item in your room.
