Disappearing Textures

So, as some of you all know I am making a map. And, I had everything saved, but I needed to place a few more custom 3d objects into the file. So I saved it. I exited out of the level and went into my Beamng folder, and I put all the files from Beamng/levels into my mod folder, and then I re-zipped it. Still, all of my textures in there. Then I go into my level and every texture is missing. None of them show up when clearly I saved them, and clearly they are in the folder. Honestly, I am really confused and do not know how to fix this. I will continue to try to fix this but for now I need your help. Thanks,

EDIT:

I do notice that in the .mis file the name of the texture had changed for some reason, so I am not sure what is happening. I changed it to what it should be.
