They took is down because it was giving Skarlet for free. This happened before with another game a few years ago. Marvel Ultimate Alliance 2. They had the Juggernaut pre-order character and the preview (which was the compatibility pack) the preview was giving
away "free" Juggernaut characters to those that didnt pre-order the game. It was taken down and fixed and then put back up and it worked the right way.
It had a glitch in it. Let you play Skarlet without paying for her. Buying Skarlet is the compatibility pack but with her included. Buying the Season Pass and then downloading her gives you the same effect. If you want only the compatibility pack, you'll
have to wait until the glitch is fixed and they reupload it. Sorry.
