+1??? Are you using a mod? I have never seen +1 or any other pluses or minuses on screen in this game. You should not need a mod to play Long Road Home. You may wish to try playing without the mod. That could easily fix any errors. If not using a mod, you can also try taking a fresh DL of the the game to ensure that your DL was not corrupted. Third party compressed files can also cause errors so that is another possibility...
I have played this amazing title since early on, like chapter three, and have never experienced a single error. When you add third party mods there is always a risk of errors or even breaking the game entirely. I do use mods/cheats in some games but have not needed or wanted one for OBD's fine work. We have a great bunch of folks here in this forum who are always glad to help whenever needed.
Hope this helps you, friend. Adventure ever on, Phat
