Problem with Kontakt 5 Automation in Cubase 9.5

I’ve never had this problem before, but suddenly I can’t do any automation on parameters in Kontakt 5. Whether with a CC assignment or just activating the write button, when I ride a filter or resonance in an app in Kontakt, afterwards Cubase doesn’t playback properly…it either just stops advancing the cursor or jumps weirdly forward. It happens in Epica and Novachord. Am I alone in having this problem? I just updated both Cubase to 9.5.50 and Kontakt to 5.8.1 (R43).
