Well, that is good news. Ideal must have made some changes for the Buchanan's some time ago. I guess now, after all these years, I can finally retire both pair of my C24 crimpers and join the plier squeezers without guilt.
I see the problem. The guy I busted had not twisted the wires. This was a "Park Ranger" job so I am not sure who the "electrician" was. They put wirenuts on all the splices before I left and all was well with the world. They did just squeeze the crimped splice on the long side and they fell off.
