Solidity 0.5 Version: Alien Codex - Requesting new instance loop
:computer: Environment Solidity 0.5 Version of Ethernaut (https://solidity-05.ethernaut.openzeppelin.com/) Ubuntu 19.10 Chrome Version 78.0.3904.108 (Official Build) (64-bit) MetaMask 7.6.1
:memo: Details When attempting to get a new instance for the Alien Codex level (19), it seems like a new transaction attempt to create a contract is issued after the previous one is mined successfully.
No other level seems to have this issue.

:1234: Steps to reproduce Press the "Get new instance" button on the Alien Codex level (19) of Ethernaut with Solidity 0.5 and confirm the transaction with MetaMask.
Thanks, I have the same experience with Alien Codex level.
I'm also having this issue.
Workaround:
The contract is being created successfully. That fact, however, is not being registered in local storage.
One may manually edit the browser's local storage as a temporary workaround. (Accessing local storage data can be done in dev tools.)

Add the appropriate key:value pair to the ethernaut_player_data_*VERSION*_*PLAYER*.emittedLevels
object.

The level key is "0xf0D6F7dA4ed4Ff54761841e497F5aFc795F04688" and the value will be the instance contract address, which can be retrieved from etherscan via the tx hash.
same here
Is still this an issue ?
works for me
closing this since we already optimized local storage management . fell free to reopen if still an issue
