Thanks for your comment! To clarify, the "check the stone again" prompt refers to the first Zuri vision scene. In version v1.1b, I made viewing this scene a requirement for entering the dungeon; it triggers automatically when you enter the office with the quest active.
However, if you update directly from v1.1 to v1.1b, the game may not recognize that you've seen the vision, potentially locking you out. To resolve this, you can:
play on v1.1 (or v1.1 fix)
start a fresh game on v1.1b
or simply use fast travel to enter the dungeon until the next patch is out with a fix.
I am working on a patch to fix this transition for v1.1 players updating to v1.1b, but it will take a few days. Sorry for the inconvenience!
