Short Update I tried to re add the old Massun Asset Pack, but It's not even showed up in the Module Manager to activate/deactivate it....
But I found the script that disables it and just changed it from false to true, and now they show up correctly if someone has the same problem you find the script under :
Saved Games\DCS.openbeta\Config, and it's called "pluginsEnabled" open it with a Lua editor and search for Massun and change false to true
Greetings
