Hello Maxi -
It’s better to make the title something related + descriptive, could be something as simple as ‘Campfires healing broken’
I just gave this a quick test in UEFN and campfires look to be working as expected. I see that you’ve marked this as ‘Creative’ but have listed PC as platform.
Just to be clear, are you placing campfire using creative mode on PC?
Are you changing any settings on the campfire?
