A while ago I posted about some unreleased pants on my twitter and today I received a message from u/Lon-ami (many thanks!) that they suddenly activated the chat codes for these in a recent patch.

Now the interesting thing is that they're located between codes from episode 4 and there's also a couple of item codes worth 2 gold 50 silver leaving me to believe this was at one point the achievement meta reward for this episode but they decided to go with Joko's Staff instead.
