I have a problem with DSS usage. I fire a probe, usually one at a time so I can see which area on the front and back of the planet my probe has hit and covered, so I can gauge how to launch the next probe. Wherever that covered area had occured, the change in colour used to stay there, but now it disappears within a second. How am I supposed to determine where to send my next probes? The covered areas are no longer covered.Once 100% surveyed, after a lot of probes,the heatmap seems to work reasonably.
