Gunrunner: Bug: Dice minigame is broken in the prologue chapter, when playing with a gamepad.
Kibou: Does this occur randomly or can it be reproduced every time you play the prologue using a gamepad?
I tried it three times and everytime it did the same thing.
The way I played was that I first armwrestled the nearby guard and then started to play the dice poker match. That way it happened every three times on a row, but I also noticed that if I just ignored the armwrestling guy and played dice poker first, then I could play the whole match from start to finish.
So it seems that the armwrestling minigame somehow affects the dice poker game, and the only way to get out of it is to force the program to close.
I hope this helps:)
