I'm out of luck, today I tried the four LR properties (47, 147, 167 and 187) and in none of them did the chest open, I'll try again another day. Thanks for your attention and answer Jaylibridges
as I understand it filed without solution ... they could at least clear the first mission from the HUD and so the person would start the missions again and remain happy in the game, but I think that this is not treated individually. Thank you for your answer and attention Rowan
I also have this problem, complete the first mission but on the second mission for several days I try to open the chest and I can't, I don't know what to do so I gave up on the game
