Apparently, when the last character in an included template is a } in a DPL query, that doesn't properly get parsed out. The workaround is to add a space before the closing }} so that you have } }} instead of }}} at the end for the template. Example of workaround fix: http://ddowiki.com/index.php?title=Arcanotechnician_enhancements&curid=35919&diff=313006&oldid=299788
Example:
Query on Category:Bugs
{{#DPL: | category = Bugs | include = {Bug}:1 | table = Page Name, Description }}
Included Bug on Foo
{{Bug|1=This is a bug.{{Ref|URL link to external source}} }}
Included Bug on Bar
{{Bug|1=This is a bug.}}
Included Bug on Baz
{{Bug|1=This is a bug.{{Ref|URL link to external source}}}}
Resulting table
Page Name | Description |
[[Foo]] | This is a bug.URL link to external source |
[[Bar]] | This is a bug. |
[[Baz]] | This is a bug.URL link to external source} |
