in #173 tefnut's call was made immune to fire and explosions, but not made immune to lightning. If you hit a mob from above there is a chance it will ricochet upwards into its own bolt and get destroyed.

2 cases of this happening. On squid (in water) this seems to be much more reliable.

Thanks for the report!
This should no longer be the case in Atum 2.1.0+ (Minecraft 1.15.2+), therefor closing.
1.12.2 is no longer receiving updates, unless something very major comes up.
