Wanted to give everyone a heads up that Quick Auctions 3 is currently posting auctions you have set at 12h auctions to 24 hours.
This is particularly concerning for items with high listing costs such as JC gems where a 12h listing fee is 1g 35s, but a 24h listing fee is 2g 70s.
I contacted Shadowed via email, the creator of the Addon and he replied saying he's making a quick fix.
So for anyone who posts tons of gems a night, just keep this in mind.
