If you go to level 10 of Last Trials, take the long rectangle and rotate it 90 degrees and fit it between the 2 leftmost bombs, the second bomb just starts moving down without even exploding! When it goes around halfway through the ground, it then blows up. What is happening here?...

See title. The inferno level set has startle sounds and stuff, but due to a quirk of my computer setup I have the game's volume sliders both at near minimum to be a normal volume. Needless to say, I slammed my headphones off the moment one of those louder sounds played.....
