Well, I goofed!
Despite numerous checks and re-checks, I made a simple but critical error when writing the assembly instructions for the Ste. Mere Eglise church model. Basically, I got the North Wing and the South Wing mixed up. The fix is also very simple, fortunately: Just switch the two wings. Basically, treat Part 2 (2A, 2B, etc) as Part 3 and vice versa.
I have only sold a couple of these kits so far, so hopefully I haven't frustrated too many people. Anyone who did buy this kit and messed up because of me, get in touch and I will send you replacement parts at no charge.
