Short description of error
I imported a collada file with several mapped and textured objects in it, each with materials for their textures and UV maps. When I joined multiple objects, the last object selected would keep its mapping, the other objects would lose their mapping. This does not happen when joining any other sorts of objects.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]

  1. Import collada file
  2. select two objects. both have UV mapping and materials and textures assigned
  3. in object mode, join the two selected objects. The last selected object will keep its mapping and the other objects joined in will not.

(See included step by step images done on test blend file with included collada file.

[Based on the default startup or an attached .blend file (as simple as possible)]
