Every time a creeper explodes, the game crashes, even without Tinkers being used in the game.

This is not mentioned in the roadmap

ScalingHealth is also required for this crash.

I have no idea what ScalingHealth is doing to the looting event but it probably shouldn't.

Report it to them.

Someone is firing the event with no damage source, should be explosion. However, easy catch for no damage source.

Should be fixed in 3.0.2.76. Comment if its not fixed.
