I stopped by at the end of the tournament and got to see some of the awesome terrain set up. Beautiful stuff.
I think one of my buildings that I donated to Yotta might have gotten mixed up with your stuff though. If you brought terrain to the 'Ard Boyz tournament, could you check to see if you have an extra three story GW building (not well painted, and based on plastruct). It may even say 'Foo' on the bottom of it. I saw it at the store Saturday night during the tournament on the shelf, but I couldn't find it when I was there on Sunday.
Thanks!
