About once every month or so, a drawer bank cabinet will not draw correctly. 

Opening the product with the Edit Design Data utility shows that the VLOOKUP LookUpTableDrawerFrontHeight functions (And all dependencies) have failed:

What's weird is that opening the LookupTableDrawerFront table and closing it "fixes" the problem. 

I don't make any edits or changes whatsoever.  All I have to do is open the table and then close it. 

I'm curious if anyone else has experienced something similar?   It's kinda hard to fix a problem when nothing is obviously wrong.
