Last night I did a little mistake and pressed the "Guide" button in the guide tab instead of "Capture" and my mount began to move even if it was parked and there was a message that I should unpark before start guiding.
Now I did the same with simulators pressing the "Guide" button when mount was parked and didn't get a message about unparking the mount before guiding but it did began drifting without unparking the mount.
This happens with KStars 3.3.9.
