Processing Issues error message

[pmolsen]

Several of my models have a rejection message "Processing Issues". The
link provided says they could be too complex etc.

They were existing models that had been accepted to the 3D layer long
ago. All I did was make some minor changes to them, one to correct a
floating problem caused by a change to the GE terrain. The other was
to correct some transparent textures that were displaying incorrectly
due to a GE bug.

None of the changes made the models any more complex. Why would they
suddenly be rejecting?

The Great Wall of China models are no more complex than 11 other
similar ones that have already been accepted.
