thank you for your message!
yes, sadly i imagine there is an incompatibility. what is happening with a lot of these helper type of mods is that they are not using the API to alter the helpers. so you get a display value that is not mapping to a created helper that can be referenced. in short, it makes anything working with the helper by reference (as you should) fail.
that said i hate the fact that this incompatibility occurs. i have looked at the idea of being able to alter this issue, but it has issues... like gender. in CB Radio Helpers it utilizes all possible helpers and notes their gender... providing a corresponding voice track.
i am working on an update which will allow end users to designate a wage for each helper, and start with a default of x% off the normal game rate. i hope that can help make this more attractive.
