^ That is my exact reasoning for it as well. It's unfortunate that 100% JJ in 2FM can't be completed in one playthrough, or it'd make things much easier, but it seems odd to end at an arbitrary "bring up the menu" point rather than an official popup within the game. If there were a trophy or something, or potentially even a character with different dialog, those would both be fairly good spots too...

Like I said, I don't run the game, but Gold/Silver crown have always felt weird to me since they're basically "partial 100% JJ" runs that we like to accept because they don't have synthesis. Since they're defined by the game, however, it seems odd to not end them when the game defines them. If the 2nd lap of final battles were different in any way, I'd be all for doing them, but they're basically just a victory lap.

Edit: Rough that my "^ That" comment landed on the next page. I was referring to Liquid's latest post at the time, which should be the last post on the first page.

That was the thing though, Plat does have a trophy popup, as does JJ 100% in 2.5. So I would consider it pretty weird to time it by trophy pop up in one version and the other be final boss, but yet still have Gold Crown be done by a pop up. This all leads to confusion throughout the categories and versions imo
