I can’t get those pastes, they are private.
Don’t worry about ilvl and stuff showing up broken on wowhead, not sure why they always have wacked out item modifications on their pages. When we read your addon data, it also contains the bonus IDs that set items to the correct ilvl, etc.
I was able to grab a last-export from those snapshots, and yeah the first one is missing e.g. that weapon the bar-fusan’s hackblade, and the second one has it. So the addon didn’t see it the first time and it did the second time. The website is reading the data correctly.
Note that inappropriate gear does not show up for a spec, e.g. when looking at Holy we won’t list strength-only weapons in the list.
I can’t really say why only some bank items don’t show up in your data… I can’t reproduce it, and I have no other reports of a similar issue happening to someone else. I have checked and the Blizzard bank API has not changed for in-game addons (probably would see lua errors if it did). I have tried everything I can think with my own characters’ bags and banks, still no problems…
If you modify your bank and/or inventory with the AMR addon window open it’s theoretically possible that the export string won’t update, but if you close the AMR addon window and open it again, it will refresh.
