Lightroom delete source files after canceled import

I am almost to upset to even write this. 

I was looking over soem old images and wanted to do some edits. First I see that for some reason lightroom thinks that my older imports are no longer in the catalog. I was a bit tired so I just pressed import for the images. I realize I dont have to do that, I can just add the catalog again. So I press cancel to do an add instead. I go to the folder and Lightroom have deleted all images in that catalog!!! How can this be? A full day of images from my trip in Africa, gone! Is this really how this works. In that case no more lightroom. 

Update: So I recreated the issue by doing a copy of a folder and then did the same procedure again and indeed it deletes all images. No questions asked just got rid of them. No move to bin nothing like it, just gone.
