When it's night time, my players (their characters) could not see NPCs until I disabled this module.

We use the PF1e game system. This module was awesome for a daytime encounter involving a darkness spell, but at night somehow the module seemed to prevent our PCs from seeing NPCs -- even though they had light sources and some had what we call Dark Vision (configured as Devil's Vision, I think, something like that).

However, when I disabled this module, everything worked normally.

The module doesn't work in 8.x
