PlayerUnknown's Battlegrounds was set to debut "something new to events" this weekend: a five to ten person limited-time squad mode named Platoon. Sadly, it's already been cancelled following a "critical error".   

"PC Players: Unfortunately, this week's Event Mode has been cancelled due to a critical error," reads a tweet posted by the PUBG Help Twitter account. "We apologize for any frustration or disappointment this has caused. Event Mode: Platoon will not be returning next week, but will return at a later date."
