Yes, that's one of the few changes we didn't share because it had business value for ShadowCores. Asking us to share everything is just ridiculous, I'm not asking anyone to do that, otherwise every server would be exactly the same. We've contributed more than anyone else to TFS. There's a pull request if you'd like to use a cast system though. I'll also tag
@WibbenZ who should read this answer too because I thought it was a too stupid question to answer before, but it appears that it's unclear to more users than just him.
