Hi Geert!
Thank you so much for helping us catch that bug!
We do have automated tests for juicer, but I had forgotten to add hiccups_diff into that.
As such, fixing a recent edge case for a different issue actually affected hiccups_diff.
Part of this bug fix actually propagated from the IGV jar, so I'm running all of our tests
before updating the jars on the main webpage. I did test hiccups_diff though and
it appears to be working. If you'd like to use the jars now, I've temporarily hosted them here:
Thank you for helping us catch that!
And please let me know if you come across any other issues.
