Workaround For Missing Texture Bug

Seems like many are having this problem of "missing" textures when creating. Here is a workaround taken from JIRA:

Workaround : Put any Texture or Snapshoot in the root of your inventory, not in any sub-folder.

No need to copy all your textures, a single one is enough to 'unlock' the selector.

Open your Textures folder, pick a single texture in it, no matter which one, right click it, Copy.

Go back to the top of your Inventory window, Right click the Inventory folder, Paste.
