2.6.24-GTNH-pre

I just noticed this, was only occurring within a fresh 2.6.1 GTNH instance that has a couple updated mods & Garden of Grind config changes.

You can see in the clip that my pages went from 5/6 to 1/2.

(I'm on this specific version because versions above 2.6.24 atm are causing me to crash with an applecore crash error, no idea why).

We've been having this same issue, on nightly 583 with removed HardcoreDarkness and removed AmazingTrophies, happening to multiple people on our server. (Sometimes the bookmarks even reappear after death)

I was able to reproduce it. will fix it.
