New problems with convoyed resources

[Aranthus]

Greatly appreciate the effort, and the difficulty of the job. Unfortunately, it appears that one maddeningly frustrating convoy glitch has been replaced with another. Now the program insists on routing the Meine Grande oil resources bound for England through the Central Atlantic instead of the East Coast, which blocks the Paramaraibo and British Guyana resources. The program then refuses to accept corrections in the convoy routes. Instead, the Meine Grande oil is treated as rail transported, so the convoy routes can't be corrected. Additionally, the program erases most or all of the default settings on all transported resources in between preliminary and final production, so that one has to do all of that work twice.
