My entire about section, except for maybe the first 5 lines or so, deleted itself D:! i KNOW i didn't do it , because when i added something to it i am quite sure i didn't delete it, as i scrolled down the page and manually deleted a small section of it... i lost all my progress stats too T.T
I don't know what else to do, if you don't have Google Cache, unless you try backarrow-ing to see if you were lucky enough to have your text still there before you submitted the cookie.
It can happen, and it saved me from many twitches of the blue vein in my head.
There's no other way I know of (other than the suggestions made by the others) to help you get it back, sorry...
But since the about section is made up of only text, an easy way to back it up is to copy/paste it into a word-like programm and save it there before you change it...
Every time I make an addition to or change in my about, I first save the whole thing on 'NotePad' and then go to work. Never failed me!
Sorry to hear this happened, SirNoobalot. Unfortunately, there's nothing in our software that actively trims the biography, nor do we keep a history of what you used to have there. Hope the suggestions about Google cache works.
