done around 2k kills, it's a hit and miss, doesn't deposit extra item when death walk is enabled, ex have Bandos blessing as only item on dw when it loots grave and bank's it doesn't bank extra blessing and take's up invy spot, sometimes when multiple deaths it will have multiple blessing in invy and will stop due to invy full, other time's when banking and withdrawing item's when it's done banking it leaves "withdraw amount" in chat and it won't enter private instance because of this and it just sits there until you manually clear it.
