It's not the problem with missing textures but broken shader links, but anyway, it never happened in earlier versions of Maya and in Maya 2015 it happens with any model I save (it happens with *.mb and *.ma files) and since I'm not using anything that is not by default included with the software I find it strange that bug count in maya rises rather than decrease... or not: the only way I found to avoid the breaking is... hide the objects you don't want broken before saving lol
