We were making a ton of retextured items. And accidently reused some filenames that were also in use in the default items.
Example:
Default Asset: DZ\characters\vests\data\chest_holster_brown_co.paa
Our Asset: DUG\client\assets\vests\chestholster\chest_holster_brown_co.paa
The result was that both items would always be the same. After renaming our asset to: DUG\client\assets\vests\chestholster\chest_holster_ourbrown_co.paa
The problem went away. Which leads me to believe textures are cached by filename and not fullpath + filename.
Please let us know if that is intentional, if not, please fix :)
