I think you're going about your tests the wrong way.

Go into some low level dungeon with a lot of good trash loot, SFK, Deadmins, etc.

Disable ALL addons except Consolid8. When I say ALL, I mean everything. Don't leave bug catcher, or anything else to match your mage's settings.

Kill some monsters and loot. If the addon works normally, you know that addon is working fine.

Next, start enabling your addons one by one, looting an item after each time and see if the error pops up. If it does, disable and re-enable <bad addon> a couple of times to be sure, and then disable everything else EXCEPT Consolid8 and <bad addon>. If the error is there, you know it's that specific addon.
