I've gotten that message twice now, once resting in Spellhold at the start of the gauntlet and the second time resting at the Vulgar Monkey in Brynnlaw.
Now, before I left for Brynnlaw, I had the party rest several, several times in rapid succesion to trigger an event in the Edwin romance. The time rested may very well have been five days and sixteen hours. But it's pretty obvious that this isn't an ER related bug. The problem, however, is that five days and sixteen hours actually passes in-game.
The only thing I can surmise is that the game got confused and decided that five days and sixteen hours is the appropriate time to rest, not eight hours. Is there a variable I can reset, or something else to be done?
Thanks!
