This is driving me crazy. I've built a robotic arm and began animating it on Friday. When I came back in today, all of the joints were mis-aligned, just about every one of them. I had to manually go back in and tweak all of their positions so they lined up again, I'm probably not nearly as accurate as I was when I modeled them. Anyone ever run into this before?
Also, there's now a line on my manipulator connecting the Y-axis with the Z-axis. It looks squarish like it's a primitive plane attached to the manipulator as reference (I guess).
If you have anything bound or any transforms on the children locked, and you froze transforms on the parents that would definitely throw the children out of whack because they cannot adjust their positions relative to the parents to keep position. They also cannot freeze since they're locked. Previous versions of maya would not even freeze transforms if items in the hierarchy were locked, I think maya 7 might try to get around that issue where possible.
