I changed the file to money_printer so I could just replace the original darkrp one, but it does not spawn or work. I have the code right and it has been checked over many times. Can someone help me? I also tried this on a server yet it still did not work.

Entity ‘money_printer’ does not exist or is not valid.

It is though, I have it created the ent in my file.
