I'm sorry, but when I spend over $40.00 for a kit, I expect to be able to build it without the hassle of trying to make their poor quality parts fit together.
I don't expect any kit to be perfect, but the warpage problem is something that can be corrected, but Moebius doesn't seem interested in correcting it. This is not the first Moebius kit that I've bought with warped parts, but it will be the last.
