In other news, the system that I face checked with basic sensors, either I didn't bother scouting the outermost planet, or that was insufficient to discover precursors, who reacted violently to the survey ship that popped over their heads. Apparently, 20 minute sub-phase and things just pop into detection range. Oops.
In other news, the size 50 commercial engine survived a cumulative 47 points of damage, and only failed when it took the last 3 points. Needless to say, there will be an inquest. And future geo survey ships may have some sensors, not to keep them OUT of danger, but to provide useful intelligence when the scouting failed.
And 250 ton scouts with basic sensors will no longer be relied upon to give an all clear for a system that was scouted with a large sub-phase increment.
