Camera postion/animations gone in all of my sequences

I’m making a feature film and have been (I thought) very organized in my sequences and using the sequence only edit options. Recently I went back to improve a part of a scene I had worked on a few weeks back only to find all my cameras in this level in their sequences have strange animations and are totally mispositoned. There’s no resemblance at all to the original camera animations so its not as if they’re just offset by 90 degrees or something.

Really hoping there’s a quick fix here as this is like… weeks of work. Camera animation a huge part of what I’m spending my time on, so this is extremely frustrating. I know duplicating sequences/animations/scenes can impact things but I didn’t do any of that…

Did you ZIP the project when you saved it?

Not sure how this could have happened, unless you unknowingly changed a variable.

Can you post a video of the animation AND the sequence player?

It could be anything.

But again, did you ZIP the project?

Did not zip the project - in my cursory searching it appears it could be an autosave bug but Im trying to rule out something on my end first. Did not zip.

The other elements of my sequence play out fine and are not distorted at all. Several of these cameras are locked in the sequencer to avoid this sort of thing and are individualized camera component assets for this one particular sequence…

Just want to exhaust everything before I literally have to reshoot and render this… Would also just like to know how to avoid it again.

I’ll post video shortly.
