Thanks for this wonderful mod!
I recognized that some people had the same struggle that the mod menu doesn't work after the game crashes or restarts - but i found a solution to make it work again everytime this happens. To fix that follow this steps:
1. Open Game, click on the mod menu icon and disable all activated mods + click on the settings wheel on the right top and disable "save feature preferences"
2. Close game - and force close it (on most devices Hold the App Icon and click "App Info" there you can force close it)
3. Open game again - the window which asks for accepting ad-data-collection or however you call it pops up again - befor you accept or choose your settings activate mods you want + "save feature preference"
4. Accept the settings of the ad window they way you choose and everything works again!
You can repeat this everytime you need to - I always check if it's working by opening a normal chest - and if the key number goes down I do this 4 steps and it works again :) (Don't wanna accidently waste diamonds or golden keys) - if you don't have any keys at the beginning try it with the energy bar - if it goes lower befor you start a round you know you have to this 4 steps!
Hope this works for others too! c:
