This bug did not happen until the I had updated the mod to v 1.2, and has been persisting through multiple new games.
Mormont will give the quest to survey the Land Beyond the Wall. I do. I gather a small force, and travel North. I find the cave, I get the prisoners, I fight the small band of White Walkers, defeat them, but when I return to Mormont, there is no option to report back to him. Just the standard "I wish to challenge you to a friendly duel/ I wish to join the Watch/ etc.". Am not sure how or why this keeps happening.
