Hey. I downloaded x-ray(auto installer if that matters) for 1.8 on minecraft. It worked fine, but all of my items contained in my chests dissappeared/missing/invisible. An hour before i downloaded x-ray i transferred it to my other laptop. It worked fine and had no troubles, no items missing. I found out that i had an extra file (r.0.-2.mca) on the computer. what is that? what happened? and how do i delete this mod? how can i recover my items? can someone please help
That website is fake, so you probably downloaded a corrupted file. You'll need to delete your .minecraft folder and run the launcher again to reset it. You'll also need to run 1.8 again. Then, download the actual mod from its forum thread and follow the installation instructions.
