Sometimes when I teleport to lumby, it logs me out. I'm not sure if it's just me so I just thought I'd stick it out there.
Nope, it's not only you. Actually, i was about to post it on bugs too, but i saw you had already posted it. I had to go online on 317 to be able to log in.
I've noticed it's been happening to a lot of people now.
I can't go back to using 317 now I've used the 508. ;D
