In Stress test 51, I can't ignite a fire in a proper fireplace of a house. I tried most houses.
Different fireplace kits, with small sticks and logs. I tried igniting with matchsticks and hand drill kit.

Upon placing in the indoor fireplace, there doesn't appear an option to ignite. Outside under a tree works.
I hope it's not taken out the game. It's nice to see the chimneys work.
