Hello there, need to deal with such thing, I created a quest, copied from quest entry 16: [Give Gerard Drink]. I changed entry and item and handled it to another creature. Yes, it shows up, it shows quest info and an Item I need to have, BUT the button "continue" is not working, button "Back" catch a bug too, after I click the first one.
