At one point when you upgrade too much, all currencies in the game gets frozen. Specifically the meat. Since everything in the game requires meat, you cannot progress after reaching level 10 although you can still level up further & use some currencies like from the frozen area where there's a medal shop & other farms, etc. Needless to say, I enjoyed my week of using the mod. It gets boring after. Uninstalled. Looking forward to play other games from this site. Arigato.
