- Contrary to what it says in the content listing, only one heavy duty card of compiled tables was actually included, according to amazon.com customer reviews. Apparently lacking spares, Catalyst Game Labs have been unable to provide extra cards, but are intending to release booklets containing them for minimal cost.
- Catalyst Game Labs has started a broken model replacement program for box sets with damaged or missing contents, particularly the plastic miniatures which are often damaged, miscast, or incomplete. The replacement program can be accessed through the Miniatures Replacement Form.
