That missiles that are close to some demigods slow down before they hit. Unfortunately this bug is still in-game, and it has the rare chance to make missiles against fast-moving or flying demigods/units "miss". Essentially the autoshot will be made by for example Torch Bearer against an angel. The shot gets into the "deadzone" where it slows down, but because the angel is moving so fast, the missile actually ends up in a "slowmotion" state with the angel moving faster than the missile, thus temporarily dodging it. The missile will take several more seconds to reach its target, but it does not always do damage.

Effectively, you can end up trying to blast down an angel at 1 health for 5-10 seconds because the missiles won't go fast all the way.
