Severity:
`fulfillRandomWords()` call may revert and the contract logic will be blocked.
Summary
The fulfillRandomWords() call may revert and the contract logic will be blocked.
Vulnerability Details
It is recommended by chainlink that the fulfillRandomWords() callback should simply store the randomness and taking more complex follow-on actions in separate contract calls made by contract owner or users. Because in case of revert VRF service will not attempt to call it a second time and contract functionality will be blocked.
