NPE when an explosive detonates

[galacticwarrior9]

Current/Expected Behavior

An NPE is thrown when an explosive detonates with no nearby entities. As a result, all Mechanics under Explosion fail to execute.

Steps To Reproduce

1. Spawn this weapon.
2. Throw it.
3. Observe the NPE in the logs and how none of the sounds play.
