Please give this issue a better title. Simply calling it 'Bug' is no help.

Thanks for reporting this! This has happened because some of your transports are extremely long and we need to add a limit on that, we should not allow that as it hits some of our internal optimizations. There isn't much we can do to recover this unfortunately. Can you return the to point before you've built the massive transports? Easy solution is to build shorter ones and have them split with mini-zipper.

Unfortunately, I don't have an older save. But I really enjoy the game, so no problem will start again. I'll try another map. Thank you for the answer and great game.

This should now be fixed in v0.4.6. Long transports are no longer allowed and if they are built they will not break the game anymore.
