so ummm yeah. i decided to get organized and moved library
items around into appropriately named folders. i go back to my
document, and every file that i moved is now gone from the
timeline. tweens, etc are still there, but the timeline shows empty
keyframes where once there was important stuff. no warnings, no
error messages, etc. is there a 'resolve library items' type
command? is this a bug? is this behavior supposed to happen? is
this a bummer? (i know the answer to the last question).
