First of all, i can not change the difficulty in one of my servers. I don't understand it, i tried everything but it doesn't work it is stuck at "Normal Difficulty" Whatever! The real problem is in my other server! My villager trade farm doesn't work! I am doing everything all right but when zombie bite villager 2nd time and then when i cure the zombie villager, it doesn't discount! I did this routine at least 5 times but still villager discounted just 1 time! It doesn't keep going. I tried it in my single player world and it worked pretty well but in server it doesn't work. If you can help me i will be appreciated. Thanks.
