N7 freezes when I hit save while writing automation

Just what the title says: if I’m writing automation to a track and I hit control + s while it’s still playing with a track in automation write mode, the screen freezes and the song continues to play for about 2 minutes. Then the song stops playing and Nuendo is completely frozen; I have to force quit via the Task Manager to close it out and I lose my work.

Anyone else have this problem? Thanks!
