The AI doesn't cheat eh? Then explain this please.
I went on in this post about how the Dread Lord AI becomes psychotically obsessed with starbases, to the point that they redeploy every single warship they have in the galaxy towards that base. https://forums.galciv2.com/?ForumID=162&AID=111194
Now.... I was playing a new game tonight, Dread Lords on parade. I had only Earth and Mars and my economy was in the crapper, so I had no choice but to build a starbase for the trade revenue modules.
Early in the game, four sectors away, the Dread Lords had popped my survey vessel and the sensor bug was in effect right there. The one where you keep sensor coverage of an area where one of your units was lost. In the middle of that area a Dread Lord fleet had been sitting for like the last 50 turns, just doing nothing.
By this point, they had been leaving me alone for most of the game. I was off in a corner by myself and they were busy with everybody else. The instant I built that new starbase, an armada of Dread Lord fleets showed up. The fleet sitting in that sensor coverage area moved towards me right after I clicked the TURN button.
There were no Dread Lord ships within three sectors of that base. I had scouts forming a picket line out to the limit of their range. There is no possibility that they detected that base on any sensors. There is no possibility that they could have known the new base was there.
So the AI doesn't cheat. Then please give a rational explanation for how they knew I had built a new starbase. I will sit patiently for the answer.
