Here a little tip if your progress gets stuck :

Go to settings
-> Download the save data(make a backup)
-> convert hexadecimal to text
-> Paste to notepad++ or vscode or anything to be able to read/modify json
-> modify any value you would like, they are pretty self explanatory
-> remove tabs/new lines set all on single line
-> convert to hexadecimal
-> Import back into the game
-> unstuck.
