Yes, one by one, individually, but the issue persisted.
I even tried to have some screenshots, but they didn't save, probably because I was in Slew mode: I managed to find out that if I taxied VERY slowly it would not crash immediately, but it would raise the nose (like if the nosewheel hit something that made the plane to pitch up until a tailstrike occurs), so at this moment I hit the Slew command and the plane "freezed" in a pitch up attitude. If I released the Slew it would probably crash. Anyway, I noticed that at that very particular position if I lowered the view to the ground I could get past the ground level and I could see some "void" space below ground level, next to an uphill that leveled to the visible ground. I suppose that this is the technique your team used in order to make the bridge (car road passing below the taxiway), but I suspect, if you allow me to, that the issue could be related to the "edge" of this "suspended ground" to the "real ground", if you will. Visually speaking there is really nothing seen, no spikes, no discontinuities, no texture breaks, etc...
