Retested with current profiling branch version: 2.18.152307

Just saying, the code snippet i posted earlier is working code prior to 2.18. Gruppe Adler and FPArma had functioning whispers like that, there was no waiting after adding or removing the player to the custom chat what so ever, all that code runs unscheduled as well.

Can confirm it works in SP until you use the command radioChannelRemove and wait before you add to the channel again.

That I am aware of, the examples and issues however are with vanilla textures.

Sure thing! Code to repro has been added!

After one and half years later. I still am hopeful this will be resolved at some point.
