Happens when pressing F9 quickly several times. Opening the developer console will work, but the local log won't be created yet. Here's a screenshot: http://prntscr.com/cho2nf/direct

Seems like a racing condition. To replicate in studio:

• Insert the DeveloperConsoleModule.lua as a script
• At line 2748 add a wait(0.1) (custom lag, as the HTTP above it errors when not online)
• At the bottom of the script, before the return statement, add:

spawn(function()
    DevConsoleModuleTable:GetVisibility()
end)
spawn(function()
    DevConsoleModuleTable:SetVisibility(true)
end)

• In the commandline, do:

loadstring(workspace.TheScript.Source)()

• Observe...

I might fix this in the next 10m or tomorrow if I don't have enough time.
