I have noticed that getting worse over time. It started when the game was released - sometimes characters would be dead but not really... but dead to some which broke auto follow because the client said nope, can't follow character is dead. Logging off and back on fixed it - as did dying again.

It only seems to have gotten worse over time though. Sometimes a character will appear to be there but really be in another spot. Sometimes you can wait and they resync other times they don't at all and appear to be in one spot but are actually not.

Sometimes (rarely) it will try to follow, turn and then follow fails. Once again, logging off and back on usually fixes it.

Not so bad that it is unworkable but another interesting quirk of the game.
