Hey man... the devs don't often speak about such things, so I don't know. I also don't know what the problem would be, since my sets are all still operable. I host a suite of modded content...
2) Modded Mercs, Bazaar, and Mines
3) Modded Pirates
4) Modded Game Content (ship components/etc.)
#1 was working except the previews, 2-4 were broke. I think I've fixed 2 and 3 using the same method I used to fix the previews. When I have everything fixed on my end, and have reuploaded, I'll be happy to help with yours. I might need you to email me all your design files to do so, you can always email me via Gauntlet@gmail.com
Here is a screen shot of the preview issue.
The folder on the left is the designs folder, where I have preview files. I've highlighted the new zip file. The Folder on the right shows the inside of the zip file, where I have also added my preview files.
