WildStar will be free-to-play in a hot minute, and that means that certain things have to change, like several of the auction house mechanics. With gear seeing stat changes and auction house access itself being reworked, it’s a system that needs to be addressed. So for the time being, the developers have shut down the auction house and the commodities exchange, with both systems coming back online with the launch of free-to-play on September 29th.
Players will be unable to interact with the two interfaces in any way while the services are offline, and any items that were listed for sale at the time of the shutdown will be mailed back once the auctions expire. It’s mostly a way of making sure that everything is lined up properly before the business model conversion takes place; you can double-check the details on the official posting.
