Correct, I did not mean to say it will solve the bug. I was suggesting a temporary work around by removing the control of jetways from the boarding script until such that Asobo fixes the bug. In the meantime, users would manually "Operate Jetways", instead of the boarding script doing this. That way, whether if the jetway is actually connected or not, it will appear to be connected and that's all that matters to the eye.
It won't change anything. Regardless if you operate the jetway manually, or let GSX operate it as part of the boarding process, the command being sent is exactly the same and, if the reason why the jetway LOOKS "disconnected", it's only due to a visual bug in the sim that results in a loss of sync between all LODs levels, but the jetway IS connected.
Again, operating it manually or not won't make any difference if you are hit by THIS bug, you might have thought it did, but you might just have mislead by having used (or not used at all) the Showcase camera to trigger different LODs switches, which would trigger the bug, since it doesn't always happen, it depends on your viewing distance, the zoom angle, how many times you went back/forth with the camera.
Note that, I'm only discussing about THAT particular VISUAL bug. That and only that.
If the issue is a different one, for example a conflict between a 3rd party airplane operating the jetway, possibly at the same time of GSX starting boarding, it is possible they might conflict with each other LOGICALLY ( so the jetway Connected/Disconnected status is really changing ) so yes, in THIS case, operating manually might fix the issue, which is a completely different one than other.
