The function liquidate, which is defined in both CrossMarginLiquidation.sol and IsolatedMarginLiquidation.sol, includes the modifier noIntermediary. This modifier prevents the use of Multisig wallets.
If the maintainer happens to use a multisig wallet they might not experience any issues until they try to call the function liquidate. At that moment they cant successfully call the function.
Recommend verifying if the prevention to use multisig wallets is intentional. In that case add a comment to the liquidate functions. If it is not intentional update the code so multisigs wallets can be supported.
