-Place TnT
-Use flint and steel
-Tnt glows
-As it's about to explode, the game just shuts down and takes me to my home screen. Every time

I'm placing it where bedrock used to be, it's next to obsidian. not sure if that's the issue? An unexplodable block next to what used to be unbreakable?

My world's 1.2G in size, perhaps it's just the coping process of updating the world that's caused this. However, I've not made a new copy yet to test it myself.

It literally only take 1 piece of TnT to shut down my game
