Yeah, that was one of the Witcher Gear schematics treasure hunt quests. I don't remember much of my original playthrough back in 2015, but I'm definitely finding that getting all those schematics and making my gear is better than most anything I've found.I think I remember that noonwraith quest!
You're definitely right, that reflection is way too strong for such a thin crescent moon, especially when its in mist or fog. I'll keep an eye out for some moon and water reflection shots, as well as that Novigrad shot you posted awhile back. I finally made it to Novigrad this week, and I forgot how big that city seems and I get turned around frequently. I also love the fact that there are no loading screens when you enter a building, like in Bethesda games.Here's an effect to watch for:
I think that's actually from the Blood & Wine DLC, but the problem could be everywhere. The new moon in the mist has a reflection in the water that is brighter than the moon itself! I guess the reflection is set for 'full moon' and never changes in the old version.
As a side note, I got another small 82 KB updated to the game this morning.
