Here is another one where a faction is stuck in its expansion with no apperant reason:https://www.dropbox.com/s/n0t4miqzwzxf320/War%20Birds.zip?dl=0
Its the Humans this time around: yo ucen see there is at least one colonisable planet in range + a Human refugee planet which they could take over any time due to the military transports they have already built
They have also not deployed new outposts for a very long time now: they had built one at the early phase but none in the last 50 turns or so which would enable them to find new colonisable planets
Just like in the save earlier, it seems they are prioratizing military ship production when there is no apperant reason for it and deprioratize expansion (outpost and colony ship)
Tested if the system has been "reserved" by another empire by colonizing it myself with the Human faction, but there was no message that a promise has been broken so guess it is not due to the new even card.
Noticed that the faction does not have Market researched yet: could it be due to this? The AI might think it makes no sense to colonize untill it can rush some markets to please the natives but why ignore the other planets then? + the natives in this particular instance have the "Friendly" attribute so no pacification is needed
