It started happening today. I installed the new version yesterday, updating from previous version.
Now I'm stuck on no way to install any mod (I tried various other mods). Only using the normal game from Play Store.
It might get reset in a few days or on the next version of the game, as it did last time I had this issue.
Perhaps the server checks all players at some specific time after the app was published, and then remembers their IDs to force them to upgrade later.
Please find what causes it and remove it , or something...
About the issue of no-damage, try to turn on the toggles as soon as you can. You might be able to reproduce it this way.
