Adding planets

Ok so I'm adding a variety of new planets and I know its nothing wrong with the mesh files or textures as the new textures and meshes for original sins planets are working. So this is what I've done so far. Ive implemented the information for the galaxyscenario in (entitydefname etc). No minidumps. I've added the string information in. No minidumps. Created a galaxyforge map with the new planets in their. And it causes a minidump as soon as it attempts toload. No other minidumps occur throughout the hole mod and I have used original sins planets as the basis (only changes I've made is using new mesh and texture). I haven't added custom icons yet but I didn't think it would be a problem. Whats wrong?
