How to reproduce

Use any gcode containing nozzle_type or numerous other placeholders as a variable.

Actual results

Expected results

It should compile normally, by default, since this is what's used with all previous Marlin(legacy) gcode in Orca Slicer.

Anything else?

It seems like a ton of gcode variables were changed to vectors, so you have to use nozzle_type[0] instead of nozzle_type for material.

This breaks a ton of gcode.

A niche issue since most people won't write custom gcode to do stuff like this (and my specific case no longer works anyway because the slicer no longer lets you select Brass as a nozzle type now, only Stainless/Hardened Steels), but still a potential cause for bugs.

This might be what's causing issues with a ton of other issues too that might just be silently failing.

I'm guessing this is a toolchanger/multitool support thing, but it really should revert to [0] for most use cases.
