Sorry I mean it works with or without the orbx add-on’s there are different versions within the zip file.
Had to make two versions because of differences around London city airport the rest of the add-on is the same.
this is the folder you would add to the community folder: thameswater for default&londoncitypack
and delete the - thameswater for Orbx EGLC add-on folder.
Of course you don’t have to use my add-on but it fixes what your seeing.
