Harmony V15 suddenly cannot move deformation points

Hi all,

I’ve kept running into an issue where I can select deformers on my rigs, but I cannot move the points or adjust the handles, they’re just frozen. Closing the program and reopening the scene fixes this issue, but it’s only a matter of time before it happens again. The last time this happened I decided to power through with other aspects of the shot and I noticed that I also could not create new contour point in my drawings, although I could move and manipulate contour points that already exists. Am I accidentally hitting a setting or hotkey?
