I find the report tab sort of useless.
It is an incomplete report of what is occuring. Especially in the Combat sections.
I have had multiple occasion in Alpha, Beta, and Solo games where a unit has been damaged or destroyed and it does not appear on the report.
I have also had it report that I had an attack with a Victory condition but the sector was now in the hands of the other player.
Personally I would rather see the resources being used to offer the Replay function be used for a more substantial Report
