Hey Dev,
Please note that there are some issues with the Re'npy's latest software update 7.4.2 as I got to know it from a wonderful developer who patiently helped me out with this issue. So, please if you are using Re'npy software to develop your game & planning to release your latest update, then please first downgrade your software to version 7.3.5 and then release it.
Also note that if you are going to release the upgrades to your game using the new software and if an individual downloads & installs it, the game will not only not work but your old saved games won't work either. So before releasing it you need downgrade the software to version 7.3.5 and then release.
I had to reset my phone and lose my saves from all the games that were installed in my phone just so that we could come up with this conclusion of mine. I wouldn't want any other patron or other players to go through the same process. I'd request you to explain this situation to the Re'npy developers team and get this sorted out.
Note: This is my experience purely based on Android phone with Android version 11. I cannot vouch for any other software or OS.
Thank you for hearing me out.
