Flip Boom Classic - Recovery after Overlap

Still a relatively new animator. Actually approved “overlap”, not realizing my work for the day would be overwritten.

Is there any way to recover ? Is there any way to find something “previous” to restore ?

Thanks !!

Is it possible to reverse the overlay of a single frame over a lot of frames ?, seems to cover them up - overlay. Based upon the number of bytes, it’s all still there but hidden.
