Midway through my bias frame sequence, 38/50 frames were saved with 0 bytes of data. When attempting to manually image and save, I was presented the following error: "Image save error: error writing to fits file." I have never had this and find it odd that the issue would pop up mid sequence, after 12 successful images taken and saved. The issue persists now beyond EKOS/KSTARS restarts and even an Astroberrry update/upgrade/dist-upgrade. Not sure how to produce a log file for it as there isn't a code given and there is nothing that populates in any of the EKOS status windows at the bottom. Willing to test with anyone who knows the steps. Thanks in advance for the help.
