custom challenge help? The Halo bulletin 4.5.12

Hi everyone, I tried to participate in this weeks custom challenge ( The Mac Cannon one) and I had a few questions.

  1. Is there a certain difficulty that it has to be?

  2. Do I have to fill in ANY constraints?

  3. And the BIG one. Why can’t I set the end date to the one in The Halo Bulletin 4.5.12?

Thanks in advance for the help!

you have it confused. you dont need to have the exact custom challenge that is seen you just need to make your own and your credits will be multiplied

Thank you! I’ll try!
