I think this is because they are currently working on the team death match game modes where your dinosaur skins will get a certain tint depending on what team you’re on. Or maybe not I’m not sure.
From what I have heard, the skins that are able to be glitched are chosen off the bat for you without your knowing. Now, I don’t know if that’s true or false, but I do notice I am only able to glitch 2-3 skins on Rex. I have not yet to try other dinos or skins, but this will make me wonder so I’ll give it try and see about making a video or replying to you directly! So as of right now, I have no answer for you on that sadly
If it’s showing a text saying the colors don’t match then the one you were randomizing is the one you have to shed into. Any other skin you didn’t randomize to get that text will not be able to be shed into. Only the one you randomize is able to be shed into
After you have managed to get one, go back to the skin you randomized on and shed into it! You will have to leave the character screen and go back into it to see if it worked. Once you shed it all the way through you should see it! If you don’t but it shows on the character screen (where the skins are) then just safe log and rejoin and should be good to go!
From what I’ve been told ppl have not gotten any, but that might’ve just been bad luck. I spent hours today trying to get one before just giving up and using my existing one XD
