GW#2, USSS-UHWW, Buddy Holly Airline, B73129
https://www.airwaysim.com/game/Routes/Planning/X/USSS/UHWW/Flown with a 733 max range option, the route goes almost at max range (2725nm).
Cargo space shouldn't be restricted, and there is still a little payload available for cargo: 330kg if I select 100% LC.
However, even if I select 100% SC, it shows 0kg allocated.
In the pic below, monday is with 100% LC (330kg), tuesday with 100% SC (0kg), and the other days with 35% LC - 65% SC.
Or is there a minimum SC weight I should supply, even in order to take a smaller amount of SC?
