I'll take a look at that mod later as I'm not familiar with it. Adjusting speeds might help a broken save I have as well. Cheers! I'll resubscribe to these assets once I play with this mod a bit.

try lowering their speed in AVO, this game sometimes has trouble getting small ships to work with the default high speed setting, that worked for me anyway

Both of these look great (railroad tug as well) but they're broken. They get stuck at the first intersection they come upon, and then clog the shipping lane for all other ships until you remove them with TM:PE. Just to be sure it was the asset and not the route, I rebuilt the route and Still had the same problem. Not sure what would be causing it, because the models load and they function until they get to the "intersection" then they just float in one spot and start stacking up onto each other.

Looks perfect, as always : )
