didn't that one have a backdoor or something
Yeah someone modified HCZ/Adam's admin event support code to include eval in it. But Badspot CRC'd the backdoor version of that support file, which would mean SuperSuit must be using a safe version.
And yeah, the problem with this add-on is that the music is being played by an object created at 0 0 0, and only has a max distance of 9001 for god knows what reason.
SuperSuit, if you could upload the copy of the add-on that you have, that would be great.
maybe you can use a server-wide music mod that uses a music brick, i'm pretty sure those have unlimited range (but no /commands)
This one just needs a tiny value change somewhere in the middle of a function.
