33 Letter to Little Rocos (致小洛克的一封信) is an open letter published by the Roco Kingdom: World development team on April 13, 2026. The letter acknowledged three live-service issues that the community had been escalating over the first three weeks after launch, and committed the team to remedies that shipped with the April 16, 2026 Magic Renewal patch. Three days separated the letter's publication from the delivery of its promises.

2323 The letter marked the first major live-service incident response of Roco Kingdom: World's post-launch cycle. The fact that the team shipped all three remedies within three days, plus issued account-wide compensation, set a precedent that subsequent patches have used as a benchmark for response speed. Community sentiment in the days after Magic Renewal launched was broadly positive, and the April 16 patch was credited with reversing a dip in retention that had started around April 11.
