We've made a change to the way we handle dueling mini-games. Previously, dueling mini-games with any amount of uses left would all be listed together with no way to determine how many uses are left.
Now, only dueling mini-games with the full 5 uses may be listed on Marketplace.tf. All other dueling mini-games may not be listed.
Additionally, we've refunded every dueling mini-game ever purchased -- totaling 104,968 mini-games with a combined value of $2,783.50 -- to the purchaser's store credit balance.
