I've only got 3 '-2's and while they all show Author ID as 'Unknown' two of the three deffinitely have 'Built In' yellow/grey laptop logo thingys and absolutely none of them were created locally....
Not locally on your machine but possibly created locally on someone else's PC and obtained by downloading content from a non dls source, still doesn't explain the yellow builtin indication though.
So went to have a look.
No -2's in TS12 here but 4 of them in 2010 just deleted one of them to see if it would, it did, as did the second I tried, but the other two as one would normally expect with the yellow indicator refused to delete, very odd indeed.
One of the -2's was a pretty basic NG route obtained from a non DLS source and to be honest not worth the disk space, not even sure why I still had it and must admit I hadn't noticed the -2 on it, anyway it's now gone.
Auran Trk01 2Trk <kuid:-2:1005> unable to delete and has a dependency of Auran Trk 01 1Trk <kuid:523:15523>
Signal MN02 <kuid:-2:1018> unable to delete and is a dependency of Harlem Line <kuid:-12:1002 and Springfield Industrial District <kuid:447264:1035>
Wagonownia <kuid:-2:1095> can delete and has a dependency of 750mm 4 <kuid:2703:38732> this is odd as the asset is a building and has a route as a dependency? looks like it was added to the kuid table probably in error, it's an item from polish Trainz.
Rotherham something or the other NG24 route, forgot to make a note when I deleted it and it wasn't on my other 2010 install to check however I'm sure there is an identical route somewhere with a different name
