Hi there.
You may probably already know this, but Forge 41.0.36+ now thrown an IllegalStateException in dev when a config option is accessed before the config files are loaded and if look like you are doing that in 1.100.7 here:

dan200.computercraft.shared.Config.sync(Config.java:297)

That basically stop us from testing with CC:T in dev (and unfortunately there is no method to turn the exception off in Forge)

Thank you
