Bot Exploit

Hi Titan, could u help to see that what the problem is?
Sometimes it doesn't sell when the bag capacity reaches my setting.
And it do not pick up some legendaries, especially when I finish great rift. There always will be one or two legendaries which won't be pick up.

Sometimes the memory of Diablo will be messed up. We think it's a bug in the game. It caused the issues you describe.
You can try to lower the bag capacity to go back to town in Settings > Loot.
