They are fine. Folks grieve differently and Animal Crossing Bells having it manifest at a wholesome game such as AC is endearing to see.Memorials:

I'd certainly encourage spoiler tags for Time Traveling as even though not everyone believes things like that a spoiler, it matters more if someone who does sees stuff they do not need to than it does if individuals who do not just have to look at something that's been spoiler tagged.

In terms of memorials, I believe it'd definitely be best to restrict them somehow. While they do not both me at the smallest and obviously people who place them don't imply them to be upsetting, you kind of have to cater to the minority because those images could be very upsetting for many people so it is better to have any repairs.

It'd only be good for transparency and means that anyone new to the game won't think that they can do things in-game that really are not possible and Cheap Animal Crossing Items then be disappointed.
