This ever happen to you?

Wow, never saw that happen. I have several I have recycled from old nimh packs that are years old and are still tough to pull apart. When you soldered them, did you let the tabs get real hot and melt the plastic a bit? I did screw one up like this once (tho the melted plastic caused it to twist the other way and be too tight to get on.)
