This is Happy Wars management team.
We implemented temporary measures for the Co-op freezing issue, and it is now effective as of August 12 (Wednesday).
Temporary Measures:
・Grim Reaper no longer appears in Co-op mode.
・Over all Co-op points that you can earn have been increased.
The freezing issue should be eased by removing Grim Reaper in the mode.
*Please go back to the Title Screen and re-enter the game in order to reflect the updated contents.
The development team is still working to find a complete solution.
Thank you for your continuous support for Happy Wars.
