You can restart, or if you are impatient like me, use this patch to delete all buildings and items (note you will have 0 coins), click here to download it.
After doing this uninstall deep town mod apk and reinstall it (this is why you need to redo steps 1-3). If anyone knows how to contact Alex please let me know.
It is most likely possible for you to restore your town through the cloud save and if that is not possible I apologize.
