I would agree that kind of response certainly leaves something to be desired. If that were at all how the Game Master replied, which is not, you embellished a good deal.
The actual conversation went like this:
GM: We can revert the sale if the token has not been claimed, but once it is claimed we are unable to revert it. Did you claim the token already?
You [Paraphrased]: Yes.
GM: I am very sorry but once that token is claimed then it is set in stone and can not be reversed.|
Our Devs try to put what safeguards they can, but there is a limit so that the game can remain playable without resorting to a version of “World of Are you sure-Craft”.
When you go to purchase an item from Thaumaturge Vashreen there actually is a pop up that not only displays what you are buying but also what you are exchanging for it. One failsafe tends to be enough as more would be redundant and really unnecessary when you then go to use said item. I am sorry that you made such an expensive error, truly, but we do ask that players take some responsibility for their actions as we also want to encourage using caution, especially on those big decisions.
Regardless, if you wish to see a change to how the item works, or what failsafes are in place, we can only encourage that you submit your feedback so that our Developers can review it.
