ReferralFeePoolV0.sol#L28 L42
In ReferralFeePoolV0.sol#claimRewardAsMochi(), path is defined as an array of length 2 while it should be length 3.
As a result, at L33, an out-of-bound exception will be thrown and revert the transaction.
claimRewardAsMochi() will not work as expected so that all the referral fees cannot be claimed but stuck in the contract.
