Somehow looking at someone else's schedule/session

[LakeYin]

Describe the bug
I recently pulled up YACS and I went to the schedule tab, only to see someone else's saved classes and schedule.

To Reproduce
I don't know how this happened, but I did use a non-RPI VPN a couple of times recently. However, I did not ever access YACS while on a VPN.

Expected behavior
I had classes and a schedule saved earlier and I hadn't cleared cookies or anything so I expected that to show up instead.

Screenshots

For context, I am a CS major and absolutely none of these classes are mine.

Desktop (please complete the following information):
I accessed YACS from Firefox.
