Why are my parties suddenly shorter?

No Special Set Items
If you had pieces or entire sets from the two Special Sets that provide Party Time, check if they are still placed in your café. Often, players unintentionally move an item from these sets back to their inventory, causing their café to lose the buffs, which results in fewer bubbles and/or Party Times.

The Special Sets are:

- Crystal Statue Set

- Ice Cream Bar Set
