The Adventure mode has been tested for more than one month on the Beta branch, and we have basically concluded that the new code modules are harmless to the original arena and the core combat system, etc. So now we have updated the adventure mode to the Default branch and continue the regular EA stage development.
Now all players can update to the latest version v0.90.04 which contains the Adventure mode. Beta test players now can switch back to the Default branch. Thanks again for your testing and valuable suggestions! :trulycheers: :youtakemyheart:
