We have identified this issue is a result of controllers whose trigger buttons have lost sensitivity due to use over time, making it more difficult to use certain button inputs in the game.
This issue was addressed in the 1.0.2 patch on Xbox One and PlayStation 4. Please update your Torment game to resolve it.
As an additional work-around, or if you are unable to update your game, we recommend switching controllers if you encounter this issue. Pressing the trigger button a bit harder might also help.
