I also have the same issue with the following...
These all show as "Installed & Out of Date (Not Obsolete)
<kuid2:276266:1291:4> NKP Caboose 400 Series - Installed, Payware
<kuid2:506034:455619:1> CN GP9 phase II (zebra) - built-in, Newer version available
<kuid2:523:19723779:1> BR Duchess Blue - built-in
<kuid2:276266:100097:3> NKP S-2 Tender - built-in
<kuid2:276266:100081:8> NKP S-2 - built-in
<kuid2:276266:100121:3> NKP 40' Boxcar - Installed, Payware
<kuid2:276266:100112:3> NKP S-2 Tender Weathered - built-in
<kuid2:276266:100110:7> NKP S-2 Weathered - built-in
<kuid2:661281:35127:5> NYC J3a-Dreyfuss - built-in
<kuid2:217537:53:5> QR PB15 (3ft 6in) - Installed, Payware
<kuid2:217537:58:5> QR PB15 Tender (3ft 6in) - Installed, Payware
<kuid:523:19721020> LMS Princess Coronation Blue - Installed, Newer version available, Payware
<kuid2:506034:455703:1> CN GP9 phase I - built-in, Newer version available
Yet "List Asset Versions" shows them all as "Not Installed, payware (not active)"
<kuid2:523:19721020:1> LMS Princess Coronation Blue
<kuid2:276266:1291:5> NKP Caboose 400 Series
<kuid2:506034:455619:2> CN GP9 phase II (zebra)
<kuid2:523:19723779:2> BR Duchess Blue
<kuid2:276266:100097:4> NKP S-2 Tender
<kuid2:276266:100121:4> NKP 40' Boxcar
<kuid2:276266:100081:10> NKP S-2
<kuid2:661281:35127:6> NYC J3a-Dreyfuss
<kuid2:276266:100112:4> NKP S-2 Tender Weathered
<kuid2:276266:100110:8> NKP S-2 Weathered
<kuid2:506034:455703:2> CN GP9 phase I
<kuid2:217537:53:6> QR PB15 (3ft 6in)
<kuid2:217537:58:6> QR PB15 Tender (3ft 6in)
Note - the QR PB15 & tender and the CN GP9's are the same as Pware & Forester1 have already mentioned. The other 9 have been like this since SP3 (build 111951)
Checking for out of date assets used to be easy, but now I have to remember that these 9 (now 13) can't be updated.
How many more will there be?
