Motion Designer

Any reason why when i reopen a motion design project it doesn’t reload everything ?
like its all there in the MD tab but nothing shows on the actual window.
also first time i rendered it moved a bunch of items to be in the center

Also it now wont render the basic of level sequencer.
Well it did at first including objects i had deleted but now it just renders black

This isn’t related to programming or scripting

feel free to show me where motion design issues / questions ago . id love to know. i couldnt find what category it falls under
