Honestly, not enough encounters this month. It makes getting everything you want from the store really hard, even if you explore all the time. With last event, all the encounters stayed around the whole month as new ones were added in periodically. This event though, encounters stay for a week before disappearing, never to be seen again it seems.

Same deal with event enemies. We see certain ones for a week before they're just gone.

It'd be nice overall if things didn't just entirely vanish, since it has gotten increasingly more difficult to get runestones with each passing week
