The Rhodes Island communications network are hacked by Reunion, who gave all Doctors an Emergency Sanity Concentrate and 20000 LMD (as an in-game mail) to "persuade" them into joining their cause.
Fortunately, R.I. managed to regain control over the network and sometime afterwards gave a Chip Catalyst, 30000 LMD, and 200 Orundum (again, as an in-game mail) to apologize for the (rude) inconvenience.
The KR server goes further by teasing an upcoming banner which features Reunion leaders (with notable exceptions to Patriot who were introduced much later, as well as Faust and Mephisto) as the rate-up Operators.
Conviction is released for CN players, who can be obtained by redeeming a special code through Bilibili.
Also, as a joke, the Heat Pump Passage is teased as an upcoming Operator.
