I've noticed the same thing with skirts.
On my most recent bot, the wedges were AGODing severely no matter what I did. Then I took off a 120cm skirt I was using for a srimech, and poof! No AGOD. Put it back on, AGOD comes back. I took it off and replaced it with a 120cm extender and then a 120cm DSL bar, and no AGOD there either.
I tried reattaching the skirt in different ways and different rotations, and every time the bot had a skirt somewhere on it, it got AGOD. Whenever it didn't have a skirt, it didn't have AGOD either.
Then I rebuilt it from the ground up (for reasons that had nothing to do with AGOD) and I was able to use the skirt srimech with no AGOD.
It would seem that certain components are "AGOD triggers", but that they don't always trigger AGOD on every bot. So far we have motors and skirts as possible AGOD triggers.
