I have a rename yahoo pipes module that looks like:

item.p.span.0 Rename title
item.p.span.1 Rename description

p.span has two children. These are evaluated in this order, and because this is a rename, p.span.0 gets deleted after being assigned to title. As this is a list, the list length decreases by one, causing the rename of p.span.1 to fail because there isn't a p.span.1 after the deletion, there's only p.span.0.

yahoo's rename module seems to handle this. I guess a work around is to reorder the renames so that the highest numbered one in each group is done first, so only the last item in the list is deleted, keeping the later indexing consistent.

I just made a bunch of updates, can you check and see if the issue is still there?
