You are just refusing to see the truth?
Yes, so they pulled a couple of images. There are numerous missing images throughout both Rover image sets. Including, Rear and Front Hazcam, Nav Cam, Panoramic.
I believe it's due to the fact that
1. There are thousands of images to catalogue and some may get lost
2. They realize at times that they already posted a particular set and so they pull it.
The reason I believe this is because in some instances you can find the exact same set of images listed under slightly different Sol numbers.
I am not saying that there aren't some crazy mysteries on Mars, but this isn't one of them.
