Placement System very well made but missing something?

Ive been looking everywhere for a good grid based placement system, as someone who does not know lua, i would love some help with this.

For some reason, when i download the uncopylocked world and play it, i get a ton of error messages for this one StringValue, that is literally named “:adhesive_bandage:”. I had no idea emojis could be used as code. but someone put this here since this game is no longer public, and i guess it means it needs repairing? or its broken?

Im very confused on this, and im very interested to know why it is like this.

Ya you can use them like that … I use them for error checking prints.
The code you have here looks like there is an error in module or a module it calls.
Pretty hard to debug them once in module form.
