I downloaded the Shinkansen 500 trains from the Download Station and for some reason, even though they're not faulty and appear in Surveyor, as soon as I start Driver, they disappear immediately. Can someone please explain to me why this is happening? They work fine in T:ANE. Also these Shinkansen 500 won't appear in Preview Asset either.
