i had almost completed the assembly when I discovered that I was short 2 screws. I placed the last ones left at opposite ends and sides of the bottom shelves in hopes that they would be spaced well enough to support the shelf. I have ordered a replacement hardware set. I would have just requested 2 screws if that were an option as I don’t need all those pieces. 
Also, after completely assembling the table, I was screwing the 6 levelers into the legs and the last leg would not accept any of the levelers. At first I thought it was the leveler, but I tried them all in that leg. I believe the hole is not correct, stripped on the inside perhaps. I would like to order a replacement corner leg.
