That's the one. I'll remake it with individual insulation. I guess
heating it up is just tipping it over the edge.

What brand of crimps are you using? Must admit to never having seen this
happen before.

I take it you are running the wires insulation into the edge of the
crimp so there is no visible ring of copper at the junction?

The other thing to do is to stagger the crimps (i.e. each wire a
different length) so that they do not overlap. That also gives a neater
join with less bulk.
