That's a very dubious error...
I'll have a look. Might be that I need to use a uint or something.

Thanks for the report. :)

I think it might be because of a plugin cause i had it working before.

Could also be that a server or umod update broke it. Still worth having a look.

Hasn’t been any updates to Oxide, only Rust.

Right, so I was converting a double value from Economics to an int32, bit strange and not sure why I did this in the past, but I now used Math.Round(balance, 2) instead.
The coming update should fix your issue. :)
