Not my tug. No credit necessary.
For blueprints, credit isn't necessary anyway. It's the nice thing to do, but not required.
Especially on builds that have gone through so many hands that the original builder's name can't be found.
The Patron-V for example went through my hands last, one of the earlier builders, hummel's before them, and then back to the original builder who left over 5 years ago whose name has been lost to time, from before there was a creator tag on builds (which is why Hummel's appears on it).

(sigh) The ship in the back is a wrecked Patron-V transport which was built by Hummel-o-War. You can find it in the prefabs as CV_Destroyed2, so the credit for the ship in the rear goes to Hummel. The tugboat in the front was my creation and can now be found in the game towing 7 different CV's behind it. (I made 7 different versions with each towing a different wreck).

This is Vermillion's Tug. All credit goes to him.

Finally got this added in. Really love the idea behind it! It will spawn in my scenario along with other Polaris freighters with the name Tugboat.

Thank you!

<chuckle> at least you do not have to trash the ship in the back, it's already wrecked.
(I remember what you did to my DROF for your scenario).

Going to add this to my scenario as a NPC Freighter!
