I don't really know about what you are talking about a broken build. It's true there is a WIP version of the map on the workshop released by RZL but i didn't tested it with people. Layout stay almost the same from what we tested on mapcore playtest a few years ago, except for a few things we discussed together with RZL. We made a list of things to change and improve and my main goal now it to make it looks really good and easy to read and understand.
For the wingman, I don't think so.
For the content, I'm not the only one who made stuff so I need to discuss with the other guys but for now i'm just thinking about finish it. It's really pissing me off to not have finished it before.
