How can I keep an archive of 0.40 in version 0.41?
what do you mean if you want to update the 040 just download the app and lick the 041 and wait and install it and open it
Just get the save files from "android → data → ncrow..." files if you can do it.
If not this, then you can see the events in the Heart icon. If the heart icon is the relationship icon, then go for the other one. You will see it there, every events.
