After finishing treasure hunt I pressed the “Guild” button from the map screen. “You are not in a guild” message appeared (I am in a guild), I pressed ok and pressed “Guild” button once again. Guild screen opened with only guild screen background (no active icons showing).
The only available option was pressing ESC button and get to the settings where I can quit the game. From the settings screen I went back to the empty guild screen and started clicking random places mostly around the corners when console screen pop out (see screenshot). Since there were some encrypted account details, I deleted it from the screenshot. Although, I have it in text format if needed.
This is the second time in a couple of days I am getting the empty guild screen, can’t say for sure what are the steps to make it happen.
