Yep, and it's stupid. The content itself is shallow, also it's immersion breaking:
Of course this festival is in winter-wonderlandy weather. So now everytime I go back to my settlement I always have snow, where I had beautiful sunshine (or rain) before.
And I just had a quest where there was a wedding in my settlement. So when this happened there was beautiful sunny weather and flower arrangements at the festial site. It screamed "springtime"!
The wedding is over after a few minutes and as you leave the festival site you literally walk against a "wall" of falling snow.
Also there doesn't seem to be a way to end this Yuletide quest. I just want it to go away.
The game has a good foundation but fails on many levels.
