Title pretty much tells everything. I've been working on the chapter's city structure for quite a while and the reason it's taken so long is definitely not designing or size issues, it's simply the busy life and not being able to do this all the time. However now the structure is ready.
Next I'll have to design the city's dialogs, which is now easy because the city won't contain any people, so basically I have to just do plans for items and even most of these are basically recycled from before (because why should I do a toilet in million ways instead of one?) and quite little of the city is actually accessible.
So when that's done, it's time for me to continue with the story and next time I'm going to report anything, it should be saying that the chapter's complete!
