So apparently if you click 'remove top accessory slot' at Bachemal it will ask you to buy a TROIKA (instead of the recovery thing) for almost a split second and it also has one of the old icons but someone told me it wasn't the icon of Troika. Here's a screenshot:

Oh well, theres even old icon of, but of Sudaruska and in other shape. I doubt if they will fix it, since this troika is not buyable and button is blocked when Troika is showing.
