Sounds like a CC-line issue. But it would be helpful if you stated which version of the Turkey track (and from where) you have. That'll make it much easier to one of our Track Masters to maybe help you.
In the meantime: No guarantee that it works as a temporary fix, since it really depends on various factors, but you could try to reduce the AI errors in the magic data and see if that has an effect.
