Could not produce class with ID 90

Hey Guys,
When I create a build with Strip Byte Code enabled I get the following error “Could not produce class with ID 90”. I could not find this under here

ClassID 90 is Avatar. I suspect you have an avatar somewhere in your data, but aren’t using it, so the stripper knows you don’t need that code. I’ll see if one of the devs can give you some advice.
