To add a tool back into your Bb course:
You may know Bb is supposed to have a specific tool, (for example SafeAssign), but you don't see it in your course content area. The instructions here will demonstrate how to add a tool back into your course.
Expand the Customization area of the control panel.
Select Tool Availability
From the list of tools, use the check boxes in the first column to make the tool available in the course. Use the check box in the right column to make sure the tool appears in your course content area:
Make sure you click the SUBMIT button after you make your selections. You can use the SUBMIT button at the top or bottom of the screen.
The image below shows SafeAssign is available, and will be available in the content areas of the course.
