I'm not entirely sure if this is the right place to report this, but here goes nothin.
This is a huge bug in the game Xenoblade Chronicles X, and I'm asking that whoever looks into this should know a lot about the game and its mechanics.
First, I would like to state that I am 2nd place on the online rankings leaderboard titled "Heavy Hitter: Maximum Damage".
In my build it requires that I stack on lots of melee attack up XX augments, making my damage output very high. In the build I use a knife, one of the knife arts named "Black Bane" (you learn it from an affinity mission) has a special effect that adds 300% damage for every debuff that is applied on the enemy at the moment you activate the art.
Using party members with specific augments, it is possible to stack on many debuffs. The problem then persists that, when there are so many debuffs that it goes so far under the enemies health bar, the game crashes. The entire screen glitches out and then goes black. The game restarts automatically as if I had just started it.
