Ok, first of all, it takes 90 days of inactivity for an account and 65 days of inactivity for a character for them to be deleted. Seeing as how I checked all of your characters late May, your stuff is fine, calm down. I said I would make sure none of your stuff got deleted, I said nothing about perming a mule for you. There wasn't anything good on that mule in the first place, I really don't understand why or how your throwing a fit about this.
Second, I have personally verified by doing a 0.2% event that you do need to beat Trema for the 100% in one game walkthrough. You'll have exactly 96.0% right after you go to do the least events on the Celsius and before you go down to the farplane and finish the game. You need to beat Trema, there are scenes before and after you beat him that are worth percentage.
