LUA error when clicking on add pull

[madar2252]

I had a Plaguefall route, I've created a new route with the data of the old one, and wanted to adjust it, when I got the following lua error. After this event the add pull button is gone. After a reload the add pull button is back, and I can see it created the new blank pull.
