I, too, have been having this issue since Saturday. The 90k boots seem to have increased with frequency over the past 2 days to the point that I can't even type a sentence in fc before I get 90k'd out again. Incredibly frustrating to suffer through hours upon hours of 1017 just to get in and 90k'd right back out for 2 days straight.

Conversely, my husband can (and has been) playing the last two days with little to no problems whatsoever. He's gotten 90k'd 2x to my 20x. He is able to play hours and hours with no problems at all, while I can't manage mere seconds of play time at this point.

You are not alone, friend. Although, sadly, I can offer no more insight than my own personal experience because I don't know the cause of this error nor how to fix it.
