After playing for 2 hours with the mod, and abandoning every quests because the Lord doesn't recognize the items, I got frustrated and stopped playing.
The Lord in every quests doesn't seem to recognize specific items.
I can only complete mob killing quests.

I have had this problem too. He gave me a pickaxe and told me to mine 16 blocks of coal ore in the region. Done, and when I try to turn it in, he says I'm 16 blocks short. It's right there! Is a mod causing the number on coal ore to change so he no longer recognizes it? Or does he see something like all coal ores and is just bugged?
