Recently discovered this neat little feature that allows the player to put powders into bowls (for glassmaking)
However - putting gunpowder into it turns the bowl into a wannabe powderkeg.

The bowl with gunpowder upon exploding will: Destroy itself, explode the surroundings, but will NEVER destroy the gunpowder in it, instead just dropping it harmlessly onto the ground as if it was destroyed

Forgot to include - tested this both on my with addons servers and a clean installation of newest TFC singleplayer - still prevails

This has been a feature for 2+ years and I'm just learning about it now...
