Hi, i did not know that this was a known bug.as i have an apm 2.6, there is no sd card. Is there a workaround for the apm 2.6?
I didn't know either.
However, I too have had some funny graphs out of the mission planner recently. Meaning that once or twice I've had to close the log viewer and reopen it to see the full time span rendered. So there might be some oddities with the log viewer sometimes.
