I originally had made just a couple custom pushback paths for the profile, but not really any other changes. Now I just tried editing the height of the starting point for the passengers at gate 2, but now when trying to board, an exception occurs and it won't board at all.
I looked at the before and after of the KROA-wcplui.ini profile. The only line that changed was
Old:
passengerentergatepos = (37.32094895047636, -79.97093296152684, 0.048)
New:
passengerentergatepos = (37.32092634991746, -79.97098046495424, 6.792000000000008)
I've attached the log file and my profile.
