Wow. Props on the author. In the last chapter I gushed a bit about how I really enjoyed it, with my only complaint that it seemed unreasonable to only have one day to prepare for foreign royalty, but brushed it off as maybe magic did it. What's the first thing they do this chapter? Have the MC comment on how unreasonable this situation is, then the others offer an excuse of magic did it. It may be a bit flimsy from a world-building perspective, but it's plausible enough that it works to create the situation the author clearly wanted, where the characters basically had this dropped on them with almost no time to prepare. Heck they even had the visitors apologize for the sudden meeting and seems they weren't entirely well prepared themselves (otherwise they probably would have had someone the Prince would trust to carry the box, well, carry the box), so there could be a good reason that this was all so short notice. Definitely bumps things up a bit in my book where the author may know what they want to do, but they think things through and tries to make sure that it works.
Edit:
@Teelaish I think that part of the issue is that no one else realized he was going to fall, but because Lynnette has seen enough kids carrying stuff like that during harvests she knew how to tell when someone was going to fall, allowing her to jump into motion before he had fully fallen. Seems reasonable enough to me that no one else in this room would have a lot of experience in knowing when someone would lose their balance like that.
