The bug

When you try to use a flint and steel or fire charge onto a block, where already fire or soul fire is, it will just waste durabilty on your flint and steel or one fire charge. This also does play the hand animation, but it doesn’t play a sound.

How to reproduce:

1. Place fire using a flint and steel/fire charge
2. Go into survival mode
3. Try to use the flint and steel/fire charge again
   Observed result: It consumed the fire charge or one durability of your flint and steal.
   Expected result: Nothing happens. You shouldn’t be able to use it again.
