We finally have an official statement from Six Flags acknowledging the issues that Riverside is experiencing:

The Company's partner in China, Riverside Investment Group ('Riverside'), continues to face severe challenges due to the macroeconomic environment and the declining real estate market in China. This has led Riverside to default on its payment obligations to the Company and, as such, the Company has delivered formal notices of default under its agreements. While the Company continues to work with Riverside and each of Riverside's governmental partners, the eventual outcome is unknown and could range from the continuation of one or more projects to the termination of all the Six Flags-branded projects in China.
This situation which has been building up throughout 2019 does not only affect Six Flags and Riverside Group but also many ride suppliers. In the future, there is potential for other Chinese developers to take over the in development parks from Riverside and rebrand them to something without Six Flags.
