What is an internal consistency error

When running the DRC in DesignSparc PCB, we got the following DRC error message...

This design appears to have internal consistency errors.
The design Signature is 168 1 10000000 00000000

We can't find any documentation about what this error means or how to fix it. When the computer was rebooted and the DRC run again, the error went away with no change to the PCB file. Can anyone explain this error message?

@mariosimoni this code indicates a net without an associated net class. It can be corrected by assigning to a net on the nets tab under design technology.

I have this error appearing too on a DRC report:

This design appears to have internal consistency errors.

The design Signature is 3049 2 00040000 00000000 .

It doesn't appear to happen on the previous revision of the design. Any idea of what it means or how to resolve it?

@S Riddel, I have checked with our developers and this error is defined as "TextWithNoLayer" of which there are two instances. As it probably cannot be seen it may be difficult to remove,if it is visible then you can assign to a layer by the shortcut "L" when it is selected. If you wish to send your design files to our support team they will examine them. You could produce Gerber plots or PDF's and check for any expected text that is missing on a layer.

Not a message I recall seeing here or on the DSPCB forum.
If you can get a design or identify the steps that consistently produce the error send it to the support team.
