Attempting to package our project, there are just two errors left that appear to refer to Error:begin and Error:end, with a stack trace in between them.

Judging by the error message, there’s an error in a file or node that doesn’t exist? There’s no mention of a specific blueprint causing the issue so any help would be much appreciated.link text

A math expression was causing issues.

I know how to fix these type errors – You can search all “Inputs” node in an blueprint editor, there must be one “Inputs” node of your blueprint that the “Inputs” node does not connect to “Outputs” node, fix it.
