UndefinedError: 'dict object' has no attribute 'nights'

You are right, it doesn't. But Jinja is smart enough to do an item lookup in this case (and vice versa) so you can always use the dot notation no matter if it's something with items or attributes.

So it's strange you are getting this error...

[ThiefMaster]

nevermind. just saw your PR, if the attributes don't exist as items either it makes sense that it breaks ;)
