@DiDA there is no need for the "No Stamina Cost for Quests" cheat. - The "No Skill Cooldown Time" cheat after using the special attacks a few times they stop reloading and you end up with no specials attacks to use, but it does show that you have SP to use, it just wont let you use the attack/technique again ever.
Once you finish the mission an error comes up " Error Code: -1" and then it wont go back to the lobby page, you have to restart the app, but you do get the rewards, you just don't know how many of them. I'll let you know what else comes up.
Thank you
