So I have written my report in order. However, some random page that is supposed to be a couple of pages before or after, comes and sits randomly in between other pages that otherwise were perfectly sequenced and flowing. This mostly happens when I switch between landscape and portrait.

I'm not sure if I make sense.

Edit: Here's the preamble if it helps.

I think a MWE would be useful here, in order to know which packages you use.

However, personal trick with landscape pages, what I do is that I rotate content in a portrait page (using rotatebox{the angle}{the content}) and after compilation I rotate landscape pages using ox's Preview app.
