I've got a transport ship that says it holds 5700 tons however it will only let me load 2x tanks which weigh 1672 tons (total 3344 tons). The ship says 1060 tons of 5700 loaded which makes no sense at all.
Shouldn’t the ship hold 3x tanks @ 5016 tons?
Also I sometimes find that transport ships on long journeys return to base half way along their route or dump the cargo in a friendly cargo and RTB. I've had a transport ship pretty much refuse to pick up these tanks, instead it just returned home and abandoned them!
Sorry if the answer is listed somewhere else on this site - I didnt manage to find it!
i had this issue as well, with helicopters in 2020 and also i had this issue when trying to load infantry onto a ship.
