Won't indicated that you finished a expedition unless you are online, if you tab out and come back after it finishes it won't indicate.

Simple solution: Show car symbol as long as you have expedition slots available, hide car symbol when they are on expedition.

Hey Gaspipe,

Thanks for the report, the icon now displays all the time  if no Expeditions are underway, hopefully that sorts the problem for you.

I actually wish you made it show as soon as there any unused slot not when all 3 slots are unused, This didn't solve the issue at all if I am being honest.
