Hi guys. I'm having a ton of fun with the game playing together with a friend. It's the first time in a very long while that games have evoked such sense of adventure and wonder. Anyway, after a couple of sessions I can no longer access the in-game survival guide. The menu opens, but as soon as I click on an item the menu disappears, and I am stuck in mouse mode until I hit escape. I'm sorry if this has been signaled before, I could not find any other threads on the subject.
