Sever has been wiped by Gubbi

You don't seem like much of a "developer" tbh.

It looks like someone with privileges ran a ULX command that displays that message and "Wipes" the server.

Probably a backdoor since you use leaks.

Send a screenshot please, and i'm say what is this

This is probably because you used leak addons, gave someone ULX permissions or something like that.

It would be fine if you show a screenshot, but it sure is a backdoor

The server is wiped. What else do you want to know?
You see, wiped means everything is gone. So unless you have a backup, you're screwed
