Cargo List without Destination

[ricardo]

I am at the stage where I cannot find what was written about the fact of having cargo in your freight-list without a destination port next to it.
How does one go about getting rid of these loads or play untill it disappears? Your comments would be highly appreciated.
Thanks Ricardo.

looks liek a problem with addons, when the stored game has a definied harbour, which is not found by the loaded addons,

I will have an update with a better error message.
