Steps to reproduce.
Activate vibrant visuals.
Change the time to midnight
Take any object that generates light and place it
Observe it closely and you will see how it will begin to darken the environment and when you stop observing it (Focus it) it will begin to illuminate the player's view well.
Observed Results:
When viewing a light placed by the player or if in a building (a house) when it is illuminated the environment always darkens making the player see the game darker than normal
Expected Results:
The lights should illuminate closed or open places at night, making visible what the player wants to illuminate for better visibility as it does in version 1.21.8102.0, the possible error is due to the change in saturation (personally I do not like the saturation that is there, it should be something more natural)
I just said In the bug report that I made brand new worlds Wich the answer to your question is no I just went to create new and pressed play and did not get any achievements I I'm still not getting any
This bug is generated for the Auto exposure, It has already been reported but has not been resolved yet, it has been around 3 to 4 versions ago. This is the control number so you can see in detail how the bug can be generated.
