Reproduced easily at each attempt; attempted day and night landing with early-access default basic probe that lands successfully at every other testing target site on Mars. (Not so on Deimos - probes always fly past, or through Deimos. Can't tell, poor visuals in open space near Deimos, accompanied by flickering - similar to flickering on Mars map involving early Russian rover landing site - prevent clear view of what is happening, so unsure whether it's a similar bug or intended as fly-by mission.)
