Reproduced on official conflict servers :

1. Spawn and go to nearest arsenal box and open it (the right one with clothes and other stuff)
2. Unequip all your clothes with right clicks on them
3. Equip any cloth that can contain items with a right click (a vest in my example)
4. Equip a radio with a right click on it (it will be put inside your equipped cloth)
5. Close the inventory window
6. Press 'G' key to open the radial menu with channel selection
7. Two additional "beta testing channel" will show up and you will not being able to select or interact with channels as normally

(pressing a 2nd time the 'G' key will fix the issue)

• You can't reproduce the steps twice in a row. Each time this "bug" is triggered, you will have to respawn to reproduce the issue.
