The compilation error you are experiencing is due to a recent Rust game update (July 2026), which completely removed all obsolete and generic versions of BaseEntity.ClientRPC.

The method is now strictly non-generic and requires an RpcTarget to specify where the network call is being sent (e.g., to the entity's network group or a specific player).

The Fix

To resolve the compilation error, replace line 45:

box.baseEntity
    .ClientRPC<string>(null, "OnRadioIPChanged", box.CurrentRadioIp);

with the updated RpcTarget syntax:

box.baseEntity
    .ClientRPC(RpcTarget.NetworkGroup("OnRadioIPChanged"), box.CurrentRadioIp);
