You do not have adequate supplies to rest here

[Script Wrecked]

I've bought a key to the common room in Regal Griffon inn in Greatgaunt.

I've entered, and press the "rest" button in the GUI.

I get the message: "You do not have adequate supplies to rest here."

What are "adequate supplies"?

Generally it means camping supplies (a Restful object) but in this case it probably just means you're not close enough to one of the cots to rest. IIRC, only two of them are Restful.

It's sometimes best to click the beds with the active spots. Also make sure that you have closed the door
