Well. To be honest, I'm not terribly surprised. When I noticed the date of the next chapter falls on christmas day, I knew it could happen... and sadly, I was correct.
Partially this is due to social obligations related to christmas, but it's also due to the chapter in question ending up being bigger than I thought it would be. I'd rather not arbitrarily cut a chapter off just to meet the deadline.
I'm also going to use that extra time to try and organize myself a little better. I'm considering some methods for faster and more efficient writing, so hopefully these kind of delays will happen a lot less in the future.
The next chapter falls on new years, but it shouldn't be a problem. I thank you all for your patience in advance.
