CG let me spend money

I have been working on Malak on and off for a month or 2 now. I have him unlocked and I was so excited when I saw the lsb for leviathan. I was going to buy it but I'm not able to now because CG set the reqs to 7 stars for Malak instead of the 5 stars needed to unlock him. I won't be able to get the materials in time to get him up to 7 stars. CG please change it to so you only b er Malak at 5 stars.
