[Rivet] Problem with yodamerge

[Hannes Jung]

Dear Rivet experts

I am using yodamerge to merge several yoda files (actually it is 1000 or so),
to get reasonable statistics in a reasonable computing time.
Sometimes I obtain strange results, like in the plot below,
where the normalization is completely off.
I am using Rivet 2.4.0, but a similar problem I had with Rivet 2.2.0.

Any idea what this could be ?

Since I am merging 1000 yoda files, it's hard to tell whether it comes from one 
specific file.... however, all jobs finished without error...

Thanks a lot
Cheers
Hannes
