You may wonder, why your trading ships wander off when buying or selling goods. The screenshots show two Food rations groups (sell option) the first one (second picture) is a huge bulk order that can be sold in Barren H. sector. The second one (first picture) is a smaller order for Food rations that your ship will sell in Fervid Corona. If you select the first one the ship will fly to different sector and sell it there (while the second option will complete you the mission with 300 FR dellivery to Fervid Corona).

i. e. be carefull what you sellect, because one station may offer several trading options but in different sectors and zones, so your Trade ship will wander off to a location you selected unknowingly...

Play hard now:)
