RocketMinipoolDelegate - Missing event in prepareVacancy
The function `prepareVacancy` updates multiple contract state variables and should therefore emit an event.\\n```\\n/// @dev Sets the bond value and vacancy flag on this minipool\\n/// @param \\_bondAmount The bond amount selected by the node operator\\n/// @param \\_currentBalance The current balance of the validator on the beaconchain (will be checked by oDAO and scrubbed if not correct)\\nfunction prepareVacancy(uint256 \\_bondAmount, uint256 \\_currentBalance) override external onlyLatestContract("rocketMinipoolManager", msg.sender) onlyInitialised {\\n    // Check status\\n    require(status == MinipoolStatus.Initialised, "Must be in initialised status");\\n    // Sanity check that refund balance is zero\\n    require(nodeRefundBalance == 0, "Refund balance not zero");\\n    // Check balance\\n    RocketDAOProtocolSettingsMinipoolInterface rocketDAOProtocolSettingsMinipool = RocketDAOProtocolSettingsMinipoolInterface(getContractAddress("rocketDAOProtocolSettingsMinipool"));\\n    uint256 launchAmount = rocketDAOProtocolSettingsMinipool.getLaunchBalance();\\n    require(\\_currentBalance >= launchAmount, "Balance is too low");\\n    // Store bond amount\\n    nodeDepositBalance = \\_bondAmount;\\n    // Calculate user amount from launch amount\\n    userDepositBalance = launchAmount.sub(nodeDepositBalance);\\n    // Flag as vacant\\n    vacant = true;\\n    preMigrationBalance = \\_currentBalance;\\n    // Refund the node whatever rewards they have accrued prior to becoming a RP validator\\n    nodeRefundBalance = \\_currentBalance.sub(launchAmount);\\n    // Set status to preLaunch\\n    setStatus(MinipoolStatus.Prelaunch);\\n}\\n```\\n
Emit the missing event.
