I hear a lot of people complain about when the Christmas Upd is coming, including the discord server. Such examples include:
"PR needs to update the game now!!!!"
"OMG PR IS ONLINE, HE BETTER RELEASE IT SOON!!"
Some have even gone far to post leak images of the boss and quest (which thankfully I missed but please don't spoil it if you had seen it).
The Christmas Upd will eventually come. PR is probably trying his hardest to make this upd go smoothly and as quickly as possible. We don't want an update that's as broken as the one we had during Halloween (1.3.8).
