-after defeating Ciadra, my potions and other consumables disappeared.... and her head is the only item there instead of only being in the quest item section (taken from the thread)
-after defeating the two Satyr miniboses the consumable items just disappeared... and Sechiron changed to Sechiron II (from the thread)
I've played up until the Den of Malfurion, I guess. I didn't continue due to items disappearing from time to time.
What I can help in your TEoP:
--> When attaching a weapon you should remove the current weapon on the hero
--> I can create a model, but too lazy. But I can help you to unattach the heroes' weapon models
