Fixed loading of 1.4 mix map (which did not have sRGB mixing option, so it is now disabled for such loaded maps)
This backfired on me. I had 1.4 Daily builds which had this option, had it already turned on (or in some cases, some modes were only sRGB, like Linear Light, so there was no check-box), and now the Hotfix turned it off for me on all materials.
Just a warning for daily build users.
