I hit Rest in Sandworm 2 and after a second there was a flurry of actions including a sand-drake getting my golem almost dead, before it finally hit me with something and 'woke me up'. It makes sense that your minions would alert you when they either charge into battle or cry out in pain, so is this a bug?
Edit: He used Eyebeam 3 times so that's at least 9 or 10 in-combat turns that passed before I was awoken.
