DUDE that happened to me (sort of) i went in a game, and my internet lagged and i went into spectator mode straight away, got connec lost and it kicked me out. displayed a weird message that looked like a packet injection and when i pressed triangle, my xp bar did the same as yours.
EDIT: forgot to mention just in case. i DID record the xp bar thingy, but that was on my old phone which i lost last week
