Guild Wars 2

Idk how it happens but I know that some items are listed below the required price and prevents further listing or buying.
I think it would be nice if the TP returned the items or allowed new listings and sales.

It’s not a bug nor does it ‘prevent further listing or buying’.

The original version of the TP allowed people to offer any price for any item. Later, a ‘floor’ was added of “vendor + 1c” which was changed to “vendor +~18%” — the first to prevent someone from listing for lower than vendor and the second to prevent anyone from netting less on the TP than they would get from the vendor.

When those changes were made, there were millions of below-permitted offers. ANet decided to let them be. Over time, plenty of people removed the offers; some didn’t. At one point, ANet decided to clear some of those listings; they got most, but not all.

What you see now are the remnants of that history.

However, there’s nothing stopping you from selling an item at whatever price you like or making an offer, save for the restriction that you have to net vendor price.

If you see anything else, use the in-game /bug reporting tool to document it (ideally with the screenshot of the TP). And, if you have time, also report it here.

tl;dr not a bug; it’s just left-over from the time when you could make below-vendor price offers.
