when i click on scenarios and try to click play to choose the Op , it does not work

@UncleSatan, Me and my friend both tested launching from the scenarios mission on the stable build and the dev branch of the game and both worked. You should have at least 6 mods. Maybe try with Zeus Enhanced installed because the CQB Interactions lists it as a dependency. Sorry it isn't working. If that doesn't work I would view your game logs, it might say something about what's going on.

I think I solved it. There was a hidden soft dependency for Western Sahara. I removed it.
