It’s now 10 days since the Consignment fee was removed from buying Krono on the Broker. This was a great change, except this has unfortunately meant that certain Krono cannot be purchased from the broker, as players receive a message stating that the item is no longer available for consignment.
NOTE: If you remove one or more Krono from the broker, you will need to camp and then login your character again for the items to appear in your Inventory and/or Currency window. For now, if you want to buy/sell Krono, you’ll need to take to the open channels, or possibly the nearest convenient tunnel.
I have bought a couple of them now since the broker fee was removed and have not had any trouble on Unrest.
Oh I take that back now that I think about it. I couldn’t buy the top one I got that error, but if I just bought the second one in the list instead it worked fine. No camping needed it was right there in my inventory.
The problem is a bit more complex than this. I have managed to purchase krono since the change. It appears that only krono placed on the broker before the change are affected. However, the problem for those krono is worse. When you try to remove a bugged krono, your krono counter is set to 0. Fortunately, this can be corrected by logging out and back in. However, the krono that were withdrawn are lost. Customer service was helpful to me when this happened, and I’m sure they will do likewise for anyone else that is affected. I just hope they fix this soon, because the market is totally screwed up right now.
I have bought and sold over a dozen on Butcherblock since the broker fee was removed.
You also can’t goto their house to buy them either
Remove ALL kronos you have on broker on ALL your character since before the problem, when you are at last character with Kronos -> restart game, then log in to each character individually and put the Kronos out on broker again. Seem to work for those i´ve asked to try it.
yeah was funny I couldn’t buy ones that were less than 700 on the broker..
