It’s absolutely atrocious that the ‘sales period has passed’ bug preventing you from removing your item from the market not only has not been fixed, it’s actually gotten worse.
It used to happen when you placed an item on the market for a period of time and it didn’t sell in that period of time, but it has started happening way before that. I placed an item on the market about 12 hours ago for ‘1 day’ and I’m now getting the sales period has passed bug.
I used to place items for 3 days just to avoid forgetting about items and having them get stuck, but even that won’t work anymore.
The fix is as simple as changing your local computer time to the server time so I can imagine it would be a simple fix from IMC’s end.
