Lines 239 to 242 in b58fd27

	function releasePolicy(uint256 bundleId, bytes32 processId)
	external override
	onlyRiskpoolService
	returns(uint256 remainingCollateralAmount)

1. remainingCollateralAmount is initialised implicitly, function always returns 0
2. no check for bundleId <-> processId correspondence. It is possible to proceed with processId of bundle[differentBundleId] and decrease active policies of bundle[bundelId] while releasing 0
