I have the default auction duration set to 48 hours in the Auctionator options. However, the auction duration when I try to auction something in the auction house defaults to 24 hours. Auctionator does not appear to be setting the default auction duration. This is in the version downloaded on 7/26/20 via Twitch.

This seemed to have broken about 2 or 3 updates ago. I have not added/changed other addons in that time so I don't believe any of them could be the problem.

No errors appear in Bugsack/grabber directly related to Auctionator as far as i can see although there are warnings of "46x (null)" that appear without any indication of the addon causing it.

All the duration/undercut features were transitioned to the new "Selling" tab because hijacking the Blizzard "Sell" tab caused throttling issues.
