design table is disappearing

At first I though I was loosing it. By I am randomly findparts that were based off design tables that are missing the designtable. The config still shows that it is driven by the table. Ihave the option under insert a new table... but I can not longeredit.

Has anybody else had their design table disappear? if so have youfound the reason for it?

Thanks
