On the info page you said helpful commands of:
/c game.speed = {target-ups} / 60
/c game.player.character.character_crafting_speed_modifier = 60 / {target-ups} - 1

When I try each I get an error:
"Cannot execute. Attempt to perform arithmetic on global 'target' (a nil value)"

You should replace {target-ups} with ups that you want. 120, for example

Normally you should not need those commands. The mod should change those when you change the mod settings, but if you enable safe mode, or unload or disable the mod without first setting the speed back to 60 UPS, and load a previous save, those can help set the game speed and crafting speed back to normal.
