Very weary, Barrie. It was a long day's drive over 165 miles round trip in the pouring rain with idiots either tailgating or stopping in front me on the highway. After I got home, I thought I'd check out the forums and be helpless before I went to bed.
I agree the kuid's might be lost in the ether which happens not just on the DLS but other sites as well. If it's nothing serious, he could replace them or just delete them. In a route, this doesn't cause too much of a problem unless it's a very specific asset that is required for the operation.
