Hello again @MrPickels, try clearing your cache and cookies and see if that fixes the problem.. also make sure you have installed the latest version of your games, also you will lose boosters you had so hopefully you weren't stockpiling them. Let me know if this works for you please.
Hey @MrPickels, last resort is to uninstall clear cache and cookies and redownload.. you will lose boosters and gold but it should solve your problem. Let me know if this solves the issue please.
