Currently CH is failing to load if its Methodscript folder already exists.
What happens if ran from commandline: https://paste.thezomg.com/75124/98625156/
What happens if loading in vscode: https://cdn.discordapp.com/attachments/612748172896370696/616677779911737374/Screen_Shot_2019-08-29_at_10.57.11_AM.png

This is on osx with any extension.
