*update*
so it appears what's doing it is my script for adding in nested submenus in the f10 coms menu.
the menus themselves work fine, but I loaded everything except that trigger and it the mission works fine, the DSMS will load properly and everything, however with that menu added in suddenly the A10 can't load the tape. I've attached below a copy of the submenu script, be gentle in your criticism of it as scripting is not my forte, about the most coding I do is hex dec on volkswagens and audi's when they come through my shop lol.
local subR = missionCommands.addSubMenu('Mission Options')
local subN1 = missionCommands.addSubMenu('Tankers', subR)
local subN2 = missionCommands.addSubMenu('SHELL 2', subN1)
local subN2 = missionCommands.addCommand('Push SHELL 2', subN2, function() trigger.action.setUserFlag('11',true) end)
local subN2 = missionCommands.addSubMenu('Arco 2', subN1)local subN2 = missionCommands.addCommand('Push ARCO 2', subN2, function() trigger.action.setUserFlag('12',true) end)
local subN2 = missionCommands.addSubMenu('TEXACO 2', subN1)
local subN2 = missionCommands.addCommand('Push TEXACO 2', subN2, function() trigger.action.setUserFlag('13',true) end)
local subN3 = missionCommands.addSubMenu('QRF Spawning', subR)
local subN4 = missionCommands.addCommand('Push QRF - Guns', subN3, function() trigger.action.setUserFlag('14',true) end)
local subN4 = missionCommands.addCommand('Push QRF - Ace', subN3, function() trigger.action.setUserFlag('15',true) end)
Thanks again.
