The reason its making unique items “disappear” is because unlike a guild bank the warbank is being treated as an extension of the character currently logged on. Unique items there can only one instance of it active so the game destroys additional copies.
You can put multiple copies of unique items in a guild bank, but consider the warbank no different than your own bank.
Honestly, I’m treating it like an account wide garbage dump that i may or may not retrieve old mats from in the years ahead, so I’m not super fussed at this stage lol
If youre losing reagents, are you crafting? Because one of the features of the warbank is to consume mats from the warbank like it does from your reagent or personal bank.
I thought I was having reagents disappear too. It turns out one of my characters is a little pot fiend and been drying, grinding and smoking all my plants. I’m going to slip some poison ivy in there and teach them a lesson.
Reminds me of the lady who kept stealing my lunch from the work fridge, but wouldnt admit it. One day I grinded up ghost chili peppers and mixed it in the dressing, she was super pissed!
This issue is actually less about what I’m doing wrong and more about getting the word out. I know it eats items. I’ve got a little process that proves it - as suggested on the bug I’ll do a video this weekend to record it and hopefully catch it in the act.
Short story is - if you’re using war bank and you think something might be missing - there’s a good chance it is.
This dose not bode well.
This is meant to be a flag ship feature of the game, not the bank specifically but the warband in general, and its still half broken.
With the rocky and unstable launch of the pre patch which is proabbly the worst i have seen in in my some 15years of playing this game. I dont think this launch is gonna go smooth.
The video linked by @Agrias clearly shows multiple items being deleted after a “Clean Up Warband Bank” function was used. Suggest not using this feature until Blizzard acknowledges and fixes this bug.
Edit: Per usual, the more people that independently report this same bug, the more likely it will get the devs’ attention for prioritizing a fix.
