hmm, very strange. I had friends check out this pack (with the required mods) and it worked just fine, maybe resub to the pack and see if that fixes if? Personally out of ideas, sorry man

yes

This is a incredibly late response @pelletier.lisa, but are you subbed to the required item I linked?

Ill have to see what is up with that when I can (Since I am currently caught up in more artistic things.), thank you for bringing this to my attention.

I get an error that says "Missing Quickmod" when I add any of these box cars to a layout. Please advise.
