This is happening with us too. Even though its a loaded mod in the server we have set up, it sometimes doesn't work. Are we doing something wrong?

Hey, Nan.
He responded to me on one of the other mods. He said that it's something to do with the Antistasi mission removing player actions. He's working on a way to fix it.

thank you for the reply my friend. I hope he gets a fix cause this is one of the most useful mods in the game!

Has this problem been fixed yet? im still getting it.

I have this issue currently, my players select drop cargo ropes, and their menu goes blank / invisable but if they just keep clicking the mouse wheel (3 times) the drops drop. Now once in flight and the object(s) are attached, to shorten them is a gamble because again you can't see that menu. It is like the main menu is there, but any sub menus are not.

Had the same issue just posting a fix that worked for me

@Jamo

You are the BEST! That fixed my issue (make sure in your Description File you have Command Menu set to true not false) this was my issue.

1.Select with middle mouse 'Deploy Cargo Ropes'
2.Scroll Back once menu disappears
3.Select (middle mouse)

FIXED!

Sorry for the necro, but since I ran into this problem recently, the solution at @jamo link is basically, double check the ACE option under User Interface for Command Menu is ON. That fixes it since the deploy for single, double, etc is not a normal scroll menu but a command menu
