finally a good reason for me to quit
(i actually quit on December 6 but i discovered this post late)

iirc it does have some special stuff, all i've seen that setting do in regular MC is add the chemistry-related blocks and some random items that i have zero idea on as to how they work

by "these" i meant the chemically accurate iron blocks

fun fact, you can get these in regular (non-education edition) minecraft too, just gotta enable a specific setting before world creation iirc

it takes 12 minutes to render this wormhole... for 4 seconds.
