How to remove a mod item from being usable in a mission?

Long story short, we're playing Antistasi with CUP and getting the infamous "Carrier in Kavala" bug. We don't want to stop using CUP, so is there a way to delete that item from the mod or disable it's use in the editor? Thanks!

​

EDIT:

After trying several different approaches (deleting the LHD vehicle file, removing it from the load order, and a few others) I finally solved the issue. Steps to fix it for those interested, however, this disables using the static CUP ships that are tied to this script.

​

1. Use PBO manager to open "cup_watervehicles_core.pbo"
2. In the functions folder, copy "fnc_initship.sqf"
3. Make a copy of this file and open it in notepad
4. Comment out the whole script by placing "/*" at the top and "*/" at the bottom
5. In PBO manager, rename the original file to "fnc_initship.sqf.bak" to keep it as a backup
6. Copy and paste the edited version into the functions folder in PBO manager
7. Close the file

This essentially disables the initialization script for the LHD ship (maybe others as well) preventing it from spawning when the game bugs and attempts to load the ship in Kavala.
