Sakura Biscuit and Sakura Trust
Sakura Biscuit's in-game item description seems to have been messed up when the detailed help text was added to describe the item's food effect.
Before the update, it read "ピヨ!", which is the way that the NPC Sakura speaks, but it is now "??!". This seems like a mistake, since it would be "Peep!" if it were translated. From a technical standpoint, this probably happened because the wrong character encoding was being used somewhere in the editing process.
Below are images of the item before and after the change:

On a similar note, there is also a small issue with the Sakura Trust's chat message: she says "Peep! Peep!", when she should say "ピヨ!" to match the Sakura NPC and the original Sakura Biscuit text.
These are both old issues, but they've bugged me for a while and it would be nice to see them fixed.
