These are the quest tasks and I recommend following them to reduce confusion with this update. There are 2 basic quest lines. You cannot do much of the second quest line anyway since you need the schematics from finishing the Academy in order to build the locomotive!
Quest line 1
Scientific Method (Completing this quest will open a branch of quests and 1 timed quest.)
Time of Discovery (3 day timed quest) Honestly, this one is quite easy to complete. The academy stages are quite small. Don’t forget to turn in your inventor’s collection for gears!
Questline 2 If you follow the quests in this order, and with the help of urgent orders, you can quite easily finish the update and timed quest quickly!
Life in Town
On the Other Bank
Two on one (completing this task will have 3 branches of quests. Into the Future and Wheels are Urgently needed are the same quest only one has a 5 day timer attached)
Engine of Progress
The Machinist Likes it
Into the Future
Wheels are Urgently Needed
