I have tried it.
The snapshot works, my applying the the change myself did not. As I could
not find a lot of other diffs in multi_index, I am somewhat baffled as to
why.
But the important thing is that the snapshot does work! Thank you.

I am not sure if the following minor issue is still multi index's fault. I
get the following 'used uninitialized' warning for inf$side (which I did
not get before):
