Maybe try after saving all sqm in MCC, exit the editor, then open that SAVED mission and delete all and paste new like you are doing. Don't forget to SAVE and don't rename it.
Just a guess, thinking its not taking cuz the fille is still open in the editor.
Hope that makes sense.
Could be several things depending on how they have it set up.
First, if someone is logged in, you cant be. They can't just exit MCC console when their done, the have to press Logout. Then someone else would have access.
Also, they my have it setup so they you have to be logged into the server to access.
Or, they could have it setup for a specific slot or even a specific player ID.
Talk to your homies.
Not sure what you mean by MCC edit menu in Zeus, MCC modules in Zeus?
You are half right and I have the same issue. However, there are 2 lines 1 is breaching ammo for placing explosives on doors. Thats the stock Claymore, can't remember if its on by default or you have to put in. But, I know that works.
What you are speaking of is a Non Lethal round, In his video does by using shotgun ammo from the the Benelli shotgun mod. Which is extremely outdated. I have tried as you have many different shotgun ammo arrays and none have worked thus far. Such as CUP and RHS no love for me either yet.
Or, if you are saying you want to breach with a shotgun, I don't think its set up to work that way.
