Have observed exactly the same phenomena with the NZGR Ab class tender ([FONT=Verdana,Arial,Tahoma,Calibri,Geneva,sans-serif]<kuid2:81997:1600:1> NZGR Ab class tender> by Billegulla) [/FONT]that worked well in T:ANE but hasn't come across to TRS19 without a fight.
It won't display in Asset Preview, either, even though it is not deemed 'Faulty' in Content Manager, but reports 10 'Warnings' (which I had planned to fix, but haven't had time to attend to yet) instead.
Which tender are you (not) looking at?
