Owner check will always fail because rarity.ownerOf always return UPPERCASE

[kur0]

Hi,

I'm trying to import my summoners into the contract, but the owner check will always fail because rarity is returning all uppercase address even I am the true owner

//(rarity.ownerOf(summonerIDs[i]) == address(this))
Error: VM Exception while processing transaction: reverted with reason string 'Ownable: caller is not the owner'
