Sure enough, all the things in the Adv. Smeltery are from scorched high oven :)
Btw: i think the lag is from that the world wasnt with bedrock at the end... get the new map its the same thread but there is a update link :)
Might add a future add/remove mod for optical reasons for guys with not so great PC build which can hand so much mods at a time.. So thinking of adding optifine optical for adding/removing it in the next update :)
~~ Update ~~
Submited a request for v1.0.1 Update on the modpack..
Included - New map edits, some mods added, and the quest book has now 1 section of quests for completeing! :)
