The Gettysburg DLC did not go as planned. Our testing, our planning ignored one major area that is a no go. Can Steam support what we are trying to do. It cannot. I'm not blaming it on anyone but me and our team. We should have caught this and known before we released.
Our plan was to put GB as DLC for WL and WL as DLC for GB. So no matter which path you choose, you can get what you want. We tried to be everything to everyone and it failed miserably. Soon after launch players pointed out these issues and research showed that there was no good solution.
In our testing we were just trying to get everything working. We mostly tested the DLC, as the stand alone game would be the same engine. We got everything working at the last hour. But just did not spend enough time integration testing. Even with all that there are still bugs we missed and it sucks. But all we can do is own up to them and fix them. We cannot move forward until we have the solid base.
Two apps cannot share the same workshop, so all mods would have to be copied and supported in two areas. The same issue comes into play in the game lobby. Although there may be a hack for it, it could get shut down in the future. So GB DLC could not MP against GB stand alone and that's not acceptable.
The only solution that solves these issues is to discontinue the GB DLC, give everyone a refund. I've already requested this from Steam and am waiting to hear back. I cannot shut down the store right now or change it.
We apologize that this happened and we are trying to make it right as quickly as possible. Thank you to everyone who jumped on this and found these issues very quickly.
