NA 2nd Edition errata suggestions

The Hasbro Q&A told of a fan-suggested LOS rules clarification the developers plan to implement. It regards placement of monsters when Hero movement reveals a new room or corridor and the Hero looks into it. So it will be officially said monsters won't block what a Hero "sees" when placing said monsters. Good.
What other rules clarifications (not house-rules) do you think Hasbro should include the new rulebook? Keller's Keep and Return of the Witch Lord clarifications/errata are also welcome.
