Quest order

I finally unlocked ATI and then Lorn shows up and wants all my hard to get materials. Should I just ignore him and focus on ATI?

I am level 90 exploring, rest 99. Should I spend the money on the first ATI or keep investing in my farm, level up more pets? Inventory 800, orchard 600 each (780 production), got the 10b storehouse upgrade.

Sawmill: 700 each or hour Steelworks: 20 pr hour Hay field: 720 pr hour Quarry: 720 pr hour 20 each chicken and cow 250 pigs
