After some more testing with my bad snap I can verify that when it’s bugged it happens 100% of the time and when not bugged, I’ve never seen the bad snap.
It becomes bugged only on lefty QBs (that I’ve seen).
It’s only certain plays that’re bugged. Again, it happens 100% on them and never on non-bugged plays.
It’s only 1 orientation of the play. I.e. it only happens if the play is flipped (and never if it isn’t flipped, or it only happens if it’s not flipped and never if it is flipped).
In Liberty’s pb I tested about 21 plays with jet motions (didn’t see it only any of the orbits I tested) and there were 2 or 3 plays that were bugged).
I’ve seen it in these plays, I don’t know how many others are broken
Gun F Twins Over: jet qb counter (flipped)
Gun ace offset: jet touch pass (not flipped)
