There is a client crash when looking at the page for the redstone timer in the Engineers Manual.
Seems to be an issue when recipe is cycling through glass panes.

I believe this may be Immersive Tech, I have submitted a new issue FerroO2000/Immersive-Tech#99 , but thought I may post it here as well
