First, as others pointed out, it's just wrong complaining for a "delay" in this reply, when you posted on a Saturday evening.
Yes, we might have spoiled people by being usually blazing fast replying during weekends, holidays and in the middle of the night but, that's not something you should take for granted, since we are real people with real lives SOMETIMES.
LSGG does not have bridges at the terminals, they are missing from the scenery. The building terminals however are there
This has been discussed so many times already: if you are missing ONLY the JETWAYS, but the rest of the scenery looks normal, the problem is NEVER the scenery, and it's ALWAYS some OTHER scenery in conflict.
Nothing, except the AFAD of another scenery can remove jetways from a scenery. In fact, when something is wrong, the only thing that remains are...jetways.
So, the only possible reason for this problem, is a conflict with the AFCAD of another scenery. Note that, if you have Aerosoft AES, a problem with its installation might caused jetways to disappear, because AES exclude them using the ONLY possible way to exclude jetways from a scenery: using an AFCAD designed to do that.
So either search for a conflicting AFCAD, or check AES (if you have it).
