Tixx got stingy with my present too, only, I wasn’t in the mists.
I went to Tixx in LA to see what was up and he offered me a present. So, I accepted it and as I did I got an error message and was sent back to the player select screen. I never got the present and Tixx has been holding out on me ever since. The chest doesn’t work and there’s plenty of space in my inventory.
