While doing monkey madness, chapter 2, I couldn't for the life of me find what was meant by the "big house with the trapdoor in the middle" without using a guide on different site (and I'd rather stay at tip.it, because you guys are the best) My confusion came from the fact that I didn't think that house was very big at all and the only mention of a trapdoor is in the temple which appeared to be a "big house" to me. Perhaps some better wording: Head west to the shed with crates and a trapdoor in the center (Pink path on map). And definitely a modification to the map: Here's a link to the current quest guide: http://www.tip.it/runescape/index.php?rs2quest_id=82
