We recently made a change to the way buy + sell orders work after official roster attribute updates.
Existing Marketplace buy and sell orders will be cancelled and refunded if they are outside of the Stubs limits set by a player item’s updated OVR. Fans can expect this for roster attribute updates going forward in MLB The Show 26.
For example, if you had a 5 Stubs buy order for a Common that got upgraded to Bronze, the order will get refunded because it’s lower than the minimum buy/sell amount for Bronze, which is 25 stubs.
