I noticed there's a listing in the bug-tracker related to this. I have several students trying to create spaceships with particle systems for the engines. Once we add a loc-rot key, the object becomes locked and can't be moved at all in later frames. Will this be able to be fixed for the next release? We've tried opening the files in 2.37, but starting to notice some backwards compatability issues.
I tried that a while ago.
Correct me anyone if this has changed, but particle emissions get calculated before animations, so they always emit from the first loc.
Animate the camera instead.
