Unable to deserialize packet with pid "xxx"

"Unable to deserialize packet with pid 247." Error in the link is a screenshot, I tried relaunching the game and it gave me about one with "pid 171" instead. I saw there were other posts about this but none had been responded to, and I didn't know if there were any recent. Character is in Act 1, only level 9.
