The config for this seems to imply he would only have emeralds in his backpack, so I assume this is a bug:

However, if this is intended... Maybe have a way to limit it only to emeralds? Cause in a modpack which modifies his trades... It can get pretty weird, even causing unstackable items to be fully stacked when they shouldn't be at all.

The items are intentional. The overstacked items are not, I will have a fix soon. Maybe I should add a config option to disable generating items and only allow emeralds?

So I've gone ahead and fixed the overstacked items issue (187c340) and I have also added a config option to generate only emeralds (66cc57b). I actually found another bug while investigating this issue.

Thank you!
