Merged post

Did you ever end up fixing it mspeedie if yes how so?

This is a problem with another type of plugin yo uuse. Its no related to Myminicopter. I have same issue

Seawheels is correct, I was able to resolve this.

If you're using https://umod.org/plugins/fuel-gauge Make sure youre using the latest version. This was how i fixed the RPC problem in my server

I had uninstalled fuel gauge, that solved it for me.
