Viewing a whole thread

Does anybody here know how I can view a thread in its entirety, I am trying to search for something in my Battery Calibration thread but its only doing it in batches, I can't even print the whole thing to a pdf file as it wont load all the pages.

I unlocked my mousewheel and went all the way to start and finish 6 times and same result, it will not show ALL the posts and its doing my nut in, I just want a local copy of the thread but for some godforsaken reason that is proving difficult on these forums.

Jellybaby this one runs on 'Flarum' so I'd have a rummage in their docs to see if you can force a full thread.

Didn't have much luck, I sent them a message, if you cant view a thread in its entirety its bad design imo.
