PC - Singularity lighting bug.

Step 1 : Place a Biopod in the basement as the Singularity.

Step 2 : Switch to the Biopod.

Step 3 : Switch back to Singularity.

Now the map will have the same lighting as the basement, including increased visual clarity. I've tested this on a variety of maps including Temple of Purgation, Family Residence, Nostromo Wreckage, RPD East, and Dead Dawg Saloon. This is enough variety to conclude that this happens on every map. If you ask me it looks gorgeous, but it makes it way too easy to see survivors. Re-entering and leaving the basement fixes the issue.
