Actually unsure why I get this error, is it because it cannot guarentee that activeMainStep - 1 is within bounds?

mainSteps is a constant right above the function

Not sure what else to provide honestly @B33fb0n3, let me you know you need to help me understand why the warning/error is given.

do you have the noUncheckedIndexedAccess flag enabled in tsconfig? this is what would make this behavior happen

Can you show the whole type? It seems like there is something missing at the end

Ill take a look when im home! Thanks for the suggestion that might be it

Will do when home, apologies
