Roxley does not have any direct involvement with group buys. We have not hand selected people running group buys, and therefore we cannot enforce rules or expectations on them. We certainly appreciate the effort they are putting in, but as a buyer, you should be aware that group buy organizers are in NO WAY affiliated with Roxley Games.
The P&P level is available to full backers on a per-request basis only (We don't just send it to everyone, regardless of whether or not they asked for it).
In order to properly control the deployment of P&P files, the only people what will officially receive the P&P files, are those who have actually backed the project on Kickstarter at a P&P or higher level.
