This has been happening ever since the update; I managed to fix it on one of my other models by continuously re-uploading my zip file. I have been reassured that the preview doesn't reflect the actual print; but when I'm working on commissions and can't print a prototype out due to time, money, or other reasons, the preview image reflects badly if the texture is distorted. Here's what it looks like, I've highlighted the badly distorted parts of the image at the side: http://i.imgur.com/jHvcI.png After 5 re-uploads so far, the texture preview is still like this. I know it's not like that in my own program, so it is a bug on Shapeways. I would appreciate any advice on how to fix this in the short term, or if it will eventually get fixed. Thanks.
