Maybe add a section on how horribly inefficient WS buildings are until chapter 15 (actually for regular WS even after that, but Magic WS become a useful building) and that every alternative source of supplies (crafting instants, AWs, event buildings, playing events for supply instants, etc) is highly preferable in order to reduce the number of WS buildings (down to zero if at all possible).
Speaking of magic buildings I didn´t see anything on them, but just avoid them early on, chapter change faster than you can upgrade them, unless you really want to spend money on them, but it´s absolutely unnecessary to have magic buildings until the higher guest race chapters. By then you probably got some for free from the spire anyway.
Only criticism: The guide seems a bit chaotic to me. hard to find specific information, it feels more like a long list of tips and tricks rather than a "guide" but it´s definitely worth the read
