I'm having trouble with Mystcraft (mystcraft-1.7.10-0.12.3.03). When I create a descriptive book and warp to the age, it warps me. However if I save and quit, if I'm in the age or not, I spawn back at the overworld spawn when I load my save. I then try to click on the descriptive book again, but the link is greyed out and unclickable. I've tried looking up this bug on Google, but I cannot find anything about it. Also, portals don't work to said ages either, and linking books to the same age are greyed out too. The ages are listed in my save, and I can see them but cannot warp to them. What is wrong?
Greyed out Link
Portal that doesn't warp.
Mods I'm using.
The save with the dimensions. However cannot warp there.
