Was this on experimental ?
I had just now a similar problem, I emptied a ammo box(not the big one, one you can find with some ammo in there) and i instantly died after pushing "empty".
I can remember that I was attacked by invisible zombies just before and I lay down as I emptied it.

Yeah had the same experience. Upvoted.

Didn't know that baked beans can add water.
