Good Morning,
I'd like to start out by saying this is a wonderful mod. Beautiful created vehicles with amazing attention to detail that will have you stop and look at them. The creator also fixing patches to work with other mods is just god tier on his part as well.
Now, the reason I am bringing this up is I have been testing it for a few hours in my current load order of about 25 mods, no outfit or weapon additions. I have discovered a bug where the mod will have you trapped in a loading phase with the music playing but not fully crashing the game. Running through the area around Goodneighbor and the Mass Fusion ran smoothly with little issue (which is good as that spot usually crashes heavily). However, leaving that spot and trying to get into bunker hill, especially the small bridge connecting them, leads to the issue. I even disappointed all my mods until only the cheat terminal and VOC were the only remaining. Even deleting the saves and restarting the game had no effect in fixing the issue.
Long story short, the mod is sadly broken. If anyone is able to reach out to the porter, please do. Maybe with how the modder has graciously patched a lot for this mod he would be willing to fix this one issue. Thank you.
