Map Device shows only gray screen

Act 3 Cruel just completed. When I interact with the map device, nothing loaded except for a gray smoky background and a single icon with a Home symbol on it.

Attempted to interact with it multiple times after checking all the NPC dialogues multiple times.

To fix the map device, I logged out to character select, logged back in, and it very slowly loaded all the assets correctly.

Same experience here. Thank you for sharing your fix, it worked for me aswell.
