But, then I tried to “Flatten” the output of the two Line components feeding the input curves to be Joined, and then it started to Join at first attempt. Should that really be needed? < scratching head >
Yes, this is an essential part of how GH works. Join joins curves by branch, that is to say all those are in a list at the same branch level. This way, you can have a tree with many branches and only the correct corresponding curves are joined for each branch level.
If you are wanting to join curves on different branch levels, you are going to need to either flatten the different lists, or use something like PathMapper to re-route one or more of the branches so that they are at the same level.
I just didn’t think of the fact that everything “multiple” is a list by nature, and that all lists in Gh (probably) are of the same type, which has branches (overlooked that). It’s intuitive once you come to think of it that way.
I have a similar problem. Two curves shall be connected by a blend curve and than be joined.
I tried hopefully all options to change directions as I thought that might be the problem.
The join items are grouped below,
I tried to minimize the items but wasn’t sure where the mistake is.

Hi, It’s my first day learning grasshopper and I’m having a problem with the join curves command.
For some reason it does not allow me to join two curves (parameter) with the command. The line that connect the canva ot the “curve” with the canva of the “join curves” disconnect if when I connect another canva.
Basically, the join curves command does not allow more than one curve to join it, so I can’t join the curves.
I looked some videos and no one seems to have this problem
