Not weird, just atypical. I build systems continuously, and sometimes there is not a complete circuit. The first thing to check when a speaker is not working is the wiring, and it is the culprit most of the time.
If you were sure that the spade was secure on all connections, then there may be a fault inside the cable. You would never see it, but moving the wire around would influence it and can cause intermittent operation. I have one speaker cable that I have used on so many systems for so many years that it has developed such a condition. I rearrange it and it works.
