These are both probably small things compared to the crashes that are still happening, but there are at least two items that do not appear to be working as intended.
The Kaptafel hat was listed in the patch notes as being a cosmetic that you could apply over another piece of equipment like an anvil, but instead it is just a hat.
And the Svarti Heirloom https://i.imgur.com/ZvH8DvC.png
It has no potential and trying to reveal it's potential will not work. I assume that it was intended to have potential due to the "potential resest not allowed line
That aside, when I tried to move to another map during act 2 (the forest chase) it instead crashed and moved to to Spinel's Map. I'm not sure how to get back to where I was.
I agree making kishin equal access it important in reboot, though I wonder if having a node only be available on a certain server is even possible to be implemented.
People have talked about having a frenzy totem becoming buyable for mesos in reboot as another option and I think this could also work if the monster spawn rates were adjusted to be the same as kishin instead of an actual frenzy totem.
Or else rework kishin away entirely (since it needs to be readjusted to help the normal servers anyways) and make a benefit of playing on reboot the increase (to kishin level) spawn rates.
