>>8118698it's a 3 length pin that's pushed into place 1 and a half units, which causes stress on the pin and is not secure. It's an illegal connection. The "potential" there was in case I was misinterpreting the connection but I'm 99% sure it's a 3l pin pushed in too far.
Also Lego uses illegal connections from time to time, most prominent in my mind is Dekar and Defilak from Mahri Nui where they also have a 3l pin pushed into a 1 unit space and making an illegal connection. They happen occasionally but they're still objectively bad.
