Another bug I've found in dungeon-battles is apparently, some issue when half the battlefield seems to be... A bit overcast? Darker than another part of it, basically.

To add to this; this effect seems to be also happening outside of dungeon battlefields altogether as well.

If I had to guess it's most likely a day/night lighting issue due to past experiences I've had with similar areas.
