Hi everyone! I'm loving Rebrickable! Thank you for everyone's efforts in building and maintaining this site. I hope to be able to contribute in due course... Currently setting myself up but I have a problem! I do hope someone knowledgeable might be able to help. I have a 3867 Baseplate 16x16, and a 14769 Round 2x2 Tile (with studholder rather than the bottom cross) - in the same colour, which looks like light blue. The problem is that the site database thinks that these pieces don't exist in the same colour. How complete and accurate is the site's set inventory? Is it known that there are gaps, so is it likely that I find that I have these kinds of glitches? Thanks very much.
