I'm having what sounds like the same exact problem. New to using the plugin, but as far as I can tell I've followed the instructions. Clearly organized all the objects into hierarchical groups which were not edited or altered once animation process begun. Get maybe 15 separate animation movements into a project, with maybe 10 camera moves, and suddenly everything goes wrong. Objects suddenly start at what should have been their end positions, and then move way past where they're supposed to. Items that were moved via two separate movements are now suddenly on the same movement, so even if I wanted to manually go through and re-adjust everything back to their correct positions, some things are now magically only able to be moved together, as if I had originally moved them together with one "Unit Movement". Objects that were rotated, say from 0 degrees to 90 degrees, now are suddenly at say, 34 degrees and the rotation movement rotates them 65 degrees. There is no rhyme or reason to it. I spent all day making one animation, only to reopen it the next day and everything had gone wrong. I figured it was a weird bug, and luckily decided I wanted to change the animation anyway, so I spent the whole next day making a new animation from scratch. All was working fine (after more than 8 hours of my time spent) until suddenly an object I was trying to move just straight up disappeared after saving its unit movement. Tried to press "undo" and most of the objects disappeared. Closed without saving, but of course auto-save is on, so apparently the damage was done. Reopened the file and the objects had reappeared, but EVERYTHING was in the wrong position and rotated incorrectly. I don't expect any solution but I have to say something to avoid putting my fist through my monitor.
