So, i just lost 160k bits on writs of faction without getting one. Accidentally doubleclicked them in the shop, reflexively tried to sell one(right click). Sold both at once for zero bits, no buyback, no writ-bonus.
Being able to sell the most expensive items in the game (so far for me) for zero bits by accident seems… of unintentional design to me. Especially when there is a buyback-option to prevent exactly these kind of situations.
