How does temples and shrines affect loyalty in a conquered city?
He meant carthaginian temples, temples of another religion, you can't upgrade them and the culture difference willl not change.

Also i beleive its all due to squalor, carthage had mostly problems of large levels of squalor, even after my massacre. First of all, what is squalor? Don't want to sound ignorant but just don't know what it is.

Secondly how do i reduce squalor once i've build up all happinnes/health buildings , some cities(carthage ) still have alot of it left. Im starting another scipii campaing today and im not leaving anything to chance, every conquered city will be put to the sword(the gods love the scipii right? )
