When you load this save, you will find the camera centered on a loose storage with priority 14 to empty. Trucks are emptying this storage, but they are mostly ignoring the priority 10 job (which has large alerts for the pick up and drop off storages). Basically, they are doing a priority 14 job over a priority 10 job. I've tagged this as severe/game breaking because if priorities aren't followed it really is game breaking. I like to use a lot of p14 and p15 jobs to keep my trucks extremely busy but with some of my unit storages this bug has been happening.
I don't know why the alert for one of the storages seems to instantly de select itself when the game loads, but it is visible in the alerts until you unpause the game.
