Invisible fire

Somehow invisible fire ended up on my house in Minecraft. The fire plays the crackling sound effect and shows the smoke particles, however, the fire texture is absent. When a player stands in this invisible fire they will catch on fire normally. It can not be extinguished by any means (including using water, placing a block on it, and punching it) and burns seemingly infinitely. I do not know how this fire came to be nor how to recreate it. I am using the default Minecraft resource pack, so a custom resource pack is not the cause.
