Recolors just can't happen

Hey everyone! I've been looking everywhere for an answer but can't find it, I recolored a whole bunch of stuff, but there is this one dress, that works amazingly in the s4s but when I use it in game my whole sim goes missing, I tried recoloring several different dresses with different meshes, and 1 of 2: my sim disappears, or my game crashes, I don't know what to do! This dress is the most important part of this set!
Edit: I forgot to say that my meshes also do the same thing when paired with my recolor inside the game, and I have redone this with 6 different meshes already
