The Christmas/holiday event started on the 1st of December 2021 and runs until the 28th of December. It consists of 10 mission.
General info:
Olivia gives the player an advent calendar, which generates a gift everyday (and has a cool-down of 24 hours). When the player opens the daily advent calendar gift, they obtain a reward for themselves and wrapping paper.
The wrapping paper can be used for the Christmas missions, that center on preparing gifts for the townspeople. The first advent calendar gift gives the payer a reward and 2 wrapping papers, to get them started on the first Christmas mission. All the next advent calendar gifts will include 1 wrapping paper (and a reward of course).
