I recently got a pure scroll as a drop, and have been trying to sell it on the TP.
However, today, I lagged, and before the sell window popped up, I clicked on the Pure Scroll (to select it as an item to put a price on), and found that I had used it.
This wasn't what I wanted, but I'm not complaining, rather, maybe:
Add a second window in the chatbox how you do with bonds, double-checking whether one wants to redeem it versus it being a typo, the same going for all high-tier mystery variants, namely:
Epic Pet Box
Pure Scroll IV
Mystery Chest
Mystery Bag
A simple fix, hoping to prevent other people from finding themselves in the same predicament.
Cheers,
