Clan mates found this shortly after server came back up. Seems when you deposit potions, instead of incrementing a dose up in your bank, it subtracts a dose.

Storing a dose from pre-pot into bank subtracts total from bank, does not add to it.

Disclaimer: I dont have prepot device. This is not my video. Sharing quickly to prevent people from losing potions.

Disclaimer 2: This video was not made by my clanmate. Rather shared by them from someone else.

EDIT: Please warn friends, clanmates, and bankstanding randoms!!

Resolution: Seems doses are still accounted for on the backend. It appeared they were being deleted as the chugging barrel was depositing them in random dosages in to your bank.

Error. Doses are still missing.

Team's been made aware and is looking into this. We think there are other dosages (3- and 2-dose potions) in the bank that are being added to instead via some odd decanting behaviour. Still something we're looking to fix but we don't believe any doses are being lost.

What's happening here is the 1-dose is being deposited, then pulling another 1-dose potion to make a 2-dose potion, which is further down in the bank and not shown in this clip. Your pots are safe (though a little rearranged...), but we'll despaghettify this and look to get it fixed!
