Hovertext Breaks Permanantly

I ran a live streaming plot overnight. When I returned in the morning, my application had crashed because my hard drive was completely full. After clearing space on the hard drive and restarting the computer, hover text no longer works. Additionally, the cursor no longer turns into a crosshair when hovering anywhere over the plot. Plotting does still work however. I can call extendTraces and see new points added to the plot. It’s just that now there is no hover text. I am running the exact same code that was previously generating new points with working hover text. I have made no changes to my code.

Does anyone have an idea of what might have caused this?
