Okay, so I have a few issues currently. One issue is that only one firefly spawns for me at night on xbox one with two friends. The other issue (and real reason for this post) is that one of my friends can only repair up to half durability. I do not understand this, two of us have repaired to full and it still doesnt let him repair to full, even after reloading the game it still isn't working.
