Solidity contract compiles in JSVM, recieves error on compile in Injected Web3 #304

The Problem

I'm investigating a scammer's "guess the number" contract that was found (here). I've made patches to the contract in the attempt to understand how the scam worked as well as how the guessing game should have worked.

The Error

When I run my contract in the JSVM it compiles and deploys without problem. When I change to Injected Web3, login to Metamask, switch to Rinkeby, then hit compile I receive:

creation of iGuess errored: call to plugin has timed out compilerMetadata - deployMetadataOf - {"from":"udapp","isFromNative":true}

Downgrading the version of the compiler doesn't do anything until 0.4.26, which doesn't compile, but gives the error:

worker undefined

I'm willing to bet the issue has to do with my code. I'm attempting to understand how to use:

abi.encodePacked(...)

The System

Compiler: 0.5.8 Language: Solidity EVM: default Injected Web3: Metamask w/ Rinkeby Firefox: 72.0.1 Windows 8.1, Intel Pentium, 2.20 GHz

Could you check for any error in the JavaScript console of the browser?

These are the warnings in the console:

MetaMask: MetaMask will soon stop reloading pages on network change. If you rely upon this behavior, add a 'networkChanged' event handler to trigger the reload manually: https://metamask.github.io/metamask-docs/API_Reference/Ethereum_Provider#ethereum.on(eventname%2C-callback) Set 'ethereum.autoRefreshOnNetworkChange' to 'false' to silence this warning: https://metamask.github.io/metamask-docs/API_Reference/Ethereum_Provider#ethereum.autorefreshonnetworkchange' inpage.js:1:2297
