I made a tutorial in my collection here

Scroll down and find Gredwitch's Base causing Lua Errors
and follow the guide.



As the author mentioned previously in both the description and discussions, not to steal their code or reupload to the workshop.
As well as their github link only giving a 404 error, meaning it was probably removed, i made a simple fix for the Null Error by adding an line before it tries to call the missing effects, which was causing the lua errors.
