Hyperion here. I was in the middle of The Thousand Maws of Toto-rak doing my low level duty roulette when I first got 90k. Tried logging back in several times and I get either 5006 or 6001.

It felt like I was lagging and rubber banding before I got hit with the 90k though. Been hoping to find any info from SE on this, but none so far.
