Please note: The first day you join the Science Career, you will get a tutorial, during this time you only have limited functions, and than after that all machines should work after you complete the tutorial. The invention machine. The invention constructor should work properly after your first day. Sometimes for it to show all the options you need to wait for a job in the task menu for it to work right. If the chat with the invent constructor is grayed out your socialization settings is too high.
