Wow this guy is showing off his Facebook ID without hiding it. Oh and your date is outdated btw. Anyways, what I think (probably wrong) is this could've been a sudden deletion/removal of cookies. Any chance of you using softwares like Fixcleaner, CCleaner, or some anti-virus softwares? They actually delete cookies, if you didn't know. I am pretty sure cookies do not affect online game accounts since they are saved directly to the server and not the computer, well it's just a server glitching thing. Nothing can be done with it.
People can easily track your ID, which means they can find your address, FB account, and so on. Look at it, his URL is bare.
