Block Party Items - Locked to Platform

If you played in the Block Party and redeemed the Block Party items, but are no longer seeing them in your inventory when playing on a different platform than the one you redeemed them on, this is working as intended.

Some items, like the Block Party items, and items purchased with real money, are locked to the platform they were redeemed on. So, launch Knockout City from the platform you originally redeemed the items on, and make sure you're logged into the same account, and you'll see the items in your inventory!
