So I had the largest empire surrender to me. Fantastic, I now have all their terrible ships and all their terrible planets. So I start going through each planet, setting them to automated governor mode as I dont need the planets which involves a fun bit of clicking per each planet, one by one. Then I have a trillion ships to worry about, many of them tiny and small. I go through the Govern section and try setting all the ships to move to a singular world so I can then begin decommissioning them all in groups because apparently there isnt a way to do it in bulk (yay!). But apparently that is not enough, as even though all the ships have move orders and a destination the game still wants me to give the ships orders (why?). At this point about 45 minutes have gone by of doing nothing but CLEANUP when bam, the game crashes to desktop. Le sigh. So, lesson learned here, dont play with the faction surrender option on as it will just introduce nothing but grief in the long term.
And I am still baffled why (unless its somewhere and I havent noticed) there is no option to mass assign planets a specific task and no option to mass decommission. And why cant an Economy governor for example be smart enough to realize that said planet wasnt build as an economy world and should be auto-rebuilt without the players input? Having to manually scrap 5-15 buildings PER WORLD just to let the governor do its job is just silly when you have many dozens of worlds.
