I mean...if you got a screenshot of the fleet you sent and fleet you wanted to catch post it here so we can see it. Anyhow no one really wants to bother themselves with this because it is just 500k points account and fleet not worth anything...attack him when he passes the threshold when retreat gets disabled and if he does it then it is clear that he is using scripts altough even with script if he has poor connection he might not be able to pull 0.5-1sec pull that easily.
I care. A cheater is a cheater regardless of their rank. These bot users and wallet warriors have essentially ruined the game. Everyone knows all the top accounts are doing one or the other, or both. But so long as they fall within certain parameters then they get away with it.
I am willing to bow out if I am indeed wrong, but even if the game did save his fleets, the game is still bugged and did not show this correctly on half a dozen combat reports. And they don't seem to care at all about the possibility of this player cheating, or the bug. That is my issue. There are only two options, he cheated or there is a bug not showing flee's correctly on the CR, and they don't care about either.
EDIT: I can post the screenshots of the 1 sec lanx and the fleet, and the CR. The CR that said the defending fleet DID NOT flee. But are screenshots with coords still against the rules? I swear that was a thing back in the day.
Regardless. I just put the fleets from the screenshots back into sim, and the 1:5.41 was total, not just against the 900 probes. It said this number on the CR only showing the 900 probes from the fleet on the lanx, but said the defending flee did not flee. So, bug on the CR, or bot. Only options.
