White light artifact coming from ground

I have a strange white light coming upwards from the ground and I can’t seem to find where it’s from. Note that I do not have any lights below the ground, therefore I do not know why this effect is happening. Also, this problem occurs in every location of my map.
Disabling my sky sphere, directional light, exponential height fog and landscape do not seem to affect the outcome.

The image below shows a room that should be completely dark but where you can still see this strange illumination.

If you have any idea where this problem might come from please let me know. Thanks

Thank you very much for your assistance. I have submitted the report

[SOLVED] For some weird reason my directional light had some real weird rotation. Make sure you build your lighting to apply the changes of your light! :expressionless:
