Not just me then. I have all EGLL Inibuilds scenery features turned off too. Restarting COUATL not helping either. Using PMDG 777 here. I finish pushback, tug leaves, then another cheerily rocks up and stops any further progress.
Did you discover the cause, and permanent fix?
EDIT: For reference, I'm using gate 532, 777-300ER. I decided to delete GSX profile files as installed by IniManager, and reinstall once more.
I just had a little look at the files it automatically installs and there appears to be a difference in content, though it doesn't leap out to me as tug related.
Previous install added: egll-iniBuilds-rwprofiles-0lliejs.py & egll-iniBuilds-rwprofiles-0lliejs.ini
Today's reinstall added:egll-iniBuilds-rwprofiles-0lliejs.py & egll-iniBuilds-rwprofiles-0lliejs-lite.ini
I honestly don't know if this relates to what I've experienced, but if it stays fixed I'm good with that.
EDIT 2: not sure that helped as it's happened again, will raise new thread
