I am unable to post a link to anything, as I have nothing to upload to. Changes I made to the tables are not the issue, as the problem is with the campaign itself. I have saved opened and saved making no alterations to the campaign, save making a new weapon available, and the errors are related to how a mission ties in to another. The only way I can get the campaign file to you would be email.
I was thinking just to make the 'loops' part of the campaign itself, and not alternative route (as I always do them anyway). I did this once with SM1-10 by just by removing the link between it and SM2-1 and the error for sm1-10 disappeared. If I can get help on how to link these together this will probably eliminate part of my problem.
