Thanks Ozzi. I’ve now tried with all addons off except Dugi, all addons on with “Out of date” unchecked and with all addons on and “Out of date” checked. It seems that Dugi is not counting ‘kills’ for credits (e.g. tooltip says 0/5 killed all the time) towards a quest and hence leaving the quest visible without showing the next quest. Dugi’s arrow seems to be coping with the problem and seems to go onto the next quest without any problem. Manually clicking the box has no effect.
