I created a test space to connect to a new MSSQL database and everything seemed to work fine. I was able to extract data and publish separately fine, and even create a report in Visualizer. I then scheduled an extract/publish and let that ran. Afterward, Visualizer and Designer is no longer there. Is there something I need to do to get it back? Never encountered this before. See image.
Here's what this space looks like.

If you look at another space, there's Visualizer and Designer there.
