While going through my items on GDstash, I realized that some items seemed to have spawned with a much lower level version of an affix compared to the item level.
Base level 94 MI has spawned with level 66/68/70/72 affixes (where a level 82 and 92 version of those affixes exist). From looking at my stash, it seems the issue has exclusively applied to prefixes as I haven’t found any high level items with low level version of a suffix.
My sample only covers MIs so I’m not sure if the same issue exists on white base items, but it’s a possibility. Affected items include Obsidian Bulwarks, Spectral War Shields and Vampiric Bonewalls, but might not be limited to those, however I do not have enough data to check if it’s happening on the others.
