Build 43993 is much better.

Any models I saved under Build 42999 are now damaged but I can import them again under Build 43993 and they render just fine except for one problem. If you look at the image attached you can see my textures for this model only nolonger matchs up were it did in previous versions.

So that's going to need fixing.

I also did some tests to see if they got the problem regarind the render bucket leaving marks and sadly that one still remains.

All in all it's better than the previos version.
