Now that the pack loaded, go to MOMO's options and disable "Using angel's chemistry machine'. This option is removing the normal chemical machines and pushes everything to the advanced chemical facilities, which makes impossible to generate sulfur early game.
Funny enough, it also makes the previously commented/removed code from running and giving an error! egg/chicken problem solve situation :)
