UDK deleted my materials?

I just deleted the BSP mesh from my scene, and added in a new one. When I tried to add my BSP materials, they just wouldn't add. When I tried different materials, they worked, but the ones I needed for the BSP mesh weren't working anymore. I tried exiting out of UDK and starting it up again and now my materials are just gone, without me having deleted them. I'll have to build them again now, and I have no idea why UDK decided to delete them. Any idea what caused this issue?

Sounds like you didn't save your package. The engine probably got confused when you were applying unsaved materials. Once the editor was closed you probably lost unsaved data and it appeared as tho the editor removed your materials.

No, the materials were saved in the package. I had opened and closed UDK with the materials saved several times before this happened.

Were they in the package of the level itself, or a stand alone package? As if it was the level itself, it will have removed it if it was no longer used.
