FWIW, my 2 cents on bridges (Chrome PC) is that if you turn a 2nd bridge just a hair too early it sort of wigs out and instead of just falling off the end of the first turning bridge, it goes straight over the 2nd (even though it's turned) and falls.

I've also seen it (once) where I'm 80% sure I turned too early, go to the middle of a bridge and stop, until I clicked it again then it zoomed to the edge and fell off.

In both situations, (particularly the one where is stopped in the middle) I'm pretty sure I jumped the gun in turning, so don't really feel like it "cheated" me, just didn't fail correctly. (and yes, I have full barred it)
