If you are referring to the TMR17 updates, then it is indeed faulty as you describe. However, if you update it in TANE SP4 then it is all OK as Hiawathamr says.
In TMR17, I have 2 other assets that show as "Out of Date" but create more faults if you update them...
<kuid:401543:2030> Ranked Session Library and <kuid2:192081:51:3> Path Control Library
I have had to leave them as is for now. I doubt N3V will ever fix them just like another 10 assets in TANE.
While the items are ok as far as Trainz Builds are concerned, there is something in the scripts that is referring to a later build/version and therefore it goes faulty. (and drags everything else down with it that is dependant on it)
Obviously, someone is not testing these thoroughly before updating them.
You can report them to the Help Desk, but I have been down that road without any luck.
