Bags not showing items, showing incorrect icons for an item, or showing an icon where there is no item

Since the TWW pre-patch, my bags have been having issues when in “single bag” mode:

  • All addons are off, have relogged/restarted the game several times.
  • Icons are showing in bag slots that do not contain an item
  • Items have incorrect icons showing for them
  • Some items are in my bag and usable/show their tool tip, but there is no icon showing at all for that item.
  • Every time I open my bags most slots are highlighted as if it was a newly looted item.

Note: None of these issues occur when bags are in split (individual bags) mode, ONLY when combined using the vanilla UI bag feature.

Had sort of the same issue. Installed the “Can I mog it?” addon and everything went blank. Could see the reagent bag but not the other bags. Deleted the addon and everything came back again. Also have the “Oilvl” addon running but this just doesn’t show the ilvl on the gear as it should. Bags are working with this addon running.
