@lanlyn thank you for your review of the video. I'm glad you enjoyed it. I don't think I could live in a place with the weather I find by default in my Sim games. Since finishing the video for Episode 20 I've gone into the Tempest mod and hopefully increased the minimum temperatures possible for Spring time and into Options to stop rain and hail. I hope that'll be enough for a more temperate climate for the rest of the videos.
I also have expended their house a bit. After the end of the video I'm currently loading I realised I needed another bedroom to allow Owen to have somewhere to sleep. And I moved the parents bedroom too. You'll see the changes in video 21 which I haven't really recorded yet. I'll start work on Oscar's Childhood tomorrow. I downloaded a lighting mod to help with that and I've written down lots of fog emitter codes that I hope will be useful. I watched a few of the fog emitter videos made by @SimEve and found them very useful. I need to watch a few more of those videos to hopefully find some more codes as I'd like some chaos in the next episode.
