many vectors I make usually get finished on the day work was started on, (except vectors with planned share dates like the an-225 and 747-8) but some vectors get forgotten about for many reasons including lack of motivation, energy, interest, or just straight up forgetting it. because of this, I have a few backlogged vectors that were never finished, the current oldest I know dating all the way back to september of 2023
The 707 was backlogged at 80 percent, only needing elevator details and a livery lol In fact, I'm looking through my unshared section in the my stuff page and I discovered that I have a backlogged version of my SD40T-2 until I actually made it using a different reference The GP30 was also originally backlogged in September, meant to be made to make an NSP locomotive project, but I instead used @amtrakman4014's since it was already available
