Here’s my list, as detailed as I can get it from memory. Guild is Niedergang, WRA-H. Nothing has been touched since the disappearances except for a test deposit/withdraw on tab 6 and the withdrawal of all gold in the bank.
Editing to add: The log entries for all the tabs seem to be correct in terms of items. I’m a little iffy on the days-since for a few bag withdrawals, but as I said, the items withdrawn/deposited are correct.
Tab 1: Miscellaneous things. DF potions, some greens, Draenor food, unopened lockboxes, MoP seeds. This is where the last deposit to the entire bank was made, 75 Dull Spined Clams. The immediately preceding activity was 15 days ago. This tab previously had less than 10 empty slots.
Tab 2: Miscellaneous blue and purple BoP which had been saved for appearance collection, DF profession accessories and tools, enchantment scrolls, various bags and reagent bags of 30+ slots. Last activity was the withdrawal of 4 Wildercloth Bags, 1+ month ago. This tab also had less than 10 empty slots.
Tab 3: Legion items. Silkweave Satchels, DF reagenta bags, as well as one (partial) stack (sometimes two) of every crafting material - fish, ore, herb, leather, teeth/horns, ench mat, cloth, etc - plus seeds from herbing. This tab was perhaps 14-16 tabs of empty space. Last activity was 1 day ago (withdrew 3 satchels), then before that 15 days.
Tab 4: BfA. As with Legion, this tab was assorted items from that xpac with at least one partial stack of every crafting mat plus bags from that xpac and other random useful items. Last activity was 3 days ago (withdrew and then deposited potions and herbs), then before that was a deposit made 15 days prior. Maybe 14 tabs empty before item loss.
Tab 5: Shadowlands xpac materials and assorted items. Last activity was 1+ month ago (a large assortment of crafting materials of all kinds). I estimate this tab had perhaps 21-25 tabs empty.
Tab 6: Dragonflight materials and ‘currency items’. This tab had been 100% full. All my fish save two partial stacks are missing, all my ores save two partial stacks are missing, every stack of leather/hide/scale/etc is now gone, and my stacks of cooking materials are gone except for three partial stacks. ‘Currency items’ were randomly hit, with about half now missing. I checked to see if it was an icon glitch one day ago after the disappearances with deposit/withdraw of Salted Venison; previously the last activity had been deposits of scale/hide/leather 15 days ago.
Tab 7: Miscellanous green items, maybe 24-30 in total, deposited there 6 days ago, plus no more than 5 full stacks of level 1 quality DF herbs/ore. All are gone but one green item.
My two other personal storage guild banks appear to be fine; I don’t know if this helps, but 8 days ago one of them had between 134-150 pet cages deposited (can’t sell my extra battle pets, the market for those is horrid) and they are still there.
Hopefully this helps somehow.
