missing artboards?
Okay. I have a bit of a problem here. It's 1am, and I saved my document with some 35 artboards. Only thing is, it saved to the same name as another file. However, thinking that it had overwritten it (and confirmed to have overwritten it!!), I closed the program to restart it since it wouldn't export as a pdf (weird bug? idk).
Normally I'd just think it was all gone for good.
Except the data is still in the file somehow? Except it won't show up when I open it. The thumbnail shows all of my artboards, and when I click "new artboard" it came up as Artboard 39 and not, Artboard 4 or 5 as it would have been if it was the original file before I had overwritten it.
Is there any hope to recover the data? In progress critique is tomorrow morning :'(
