Yes, I know about this one. It's an artifact of the performance
improvements I pushed to the production server (the one you use). It can
be fixed quickly -- like by Friday.

Now that you've mentioned it, I could have predicted this error. I'll add
a unit test for overlaps+inside combined queries. So the good news is
that once I fix it and add a test for this type of error, it won't happen
The bad news is that this fix may take several days as I have several
other urgent things in my queue.

These are new errors as of last week, when I pushed out the new range
