Game Breaking Regression since v5, can't ship until it is fixed

I have been waiting on a fix for this every since upgrading to v5. I have also filed a bug on it and seen others file bugs on it that get closed as dups. It breaks my game because I use the triangle index to test what material is hit. Materials in my game dictate if the player should do things like orient to the surface, crawl up a wall, or slide because it is ice. The index being wrong means that is totally broken. I still have more to do but hope to be in a position to ship my first game in November, my birthday month but this bug means I can't. Please vote for it.

Unity devs, please fix it for 5.3
