Invalid cast from alloc::string::String to alloc::string::String #47

Closed mjhouse closed 2 years ago

mjhouse commented 2 years ago

I receive the following error while using the bevy_spicy_networking crate any time I try to send a message with a string in it. I'm not sure why it happens. It seems as if it shouldn't, since it's from String to String.

thread 'tokio-runtime-worker' panicked at 'invalid cast: alloc::string::String to alloc::string::String',

I published 0.3.17 removing the panic.
