Grinder crashing my game

So in the past when I’ve wanted new legendary weapons at my level I have
been using 3 purples to grind an orange and then grinding 3 oranges
until I got what I wanted, today I’ve gone to gain to level 57 oranges
and everytime I try to grind 3 purples it crashes my game, what is
happening?

Sounds like the hotfix to prevent this didn’t get applied when you launched the game. Do you have an active internet connection? Apparently, if you hit “continue” too soon, you can also start playing before the hotfixes are fully applied.
