When I open the Lexica Botania, the entire game begins to lag heavily. By that I mean that everything gets sluggish. Mouse movement, keyboard input, etc. The book opens and you can somewhat navigate around it. However after a short period it begins to be nearly non-responsive. It does so in any menu. That is, the book menu, inventory screen, or even the pause/alt tab screen.

I have moved around and reloaded the world fine. And everything works brilliantly before opening the book. No lag, no issues.

SSP, Slightly altered Infinity (added Iguana Tinker Tweaks and Minechem).

I have the log for the relevant time period, but I'm unsure of how much use it is.

All it really shows is the loading of the world, a bit of moving and looking around, opening the book, and then alttabbing. I can give full load-up sequence log if that would help more.
