Seems that this chapter's quests will end for me the same way as previous chapters.
By having the choice between
Spend absurdly long time in the chapter
and
Build absurdly big fleet,
I now have hardly any space left in the city and have hardly population for upgrading Main Hall (many others have gone even further and have negative population - I have seen cities with over -200K pop).
Therefore I will not be able to finish the quests, since I will do all upgrades after finishing the research (after I get rid of the fleet).
And since there is a quest(s) asking upgrading buildings followed by a quest(s) asking producing guest race goods, I'll not do that quests, since by that time, the fleet is already gone (and I won't need it's products).
