Ok, sorry I misunderstood.
Anyways I am now 4 years further into the game now year 37. My shipping lines developed further.
Corporations: Ships Tonnage Increase Ships Increase Tonnage
Dangel Transport Corporation 298 11563400 52,82% 35,33%
Trattner Company 233 10005600 70,07% 61,00%
Welke Colony Group 018 611200 20,00% -9,92%
Hamburg Lines 023 1059450 228,57% 251,04%
Also depending vastly on shipping lines got me a side effect. At 30 Day increments I lose 2333 wealth per month. At 1 Day increments I gain 3133 wealth per month. I cannot longer play on longer increments otherwise I will go bancrupt
Also something is strange. All Civ Space Liners are doing their thing. Also 90% of the Colony Ships do their job. But 90% of the Freighters are idling. Something must be broken regarding Freighter spawning.
A bit offtopic, but I also got 135 Civ Mines. Are shipping lines and Civ Mine spawns related?
