[Gameplay] Blue buff health not resetting

This happened in a game last night I was playing with some friends. There was a fight around blue buff and a battle back and forth for it both teams eventually left the blue and it reset. My jungler went back to blue after healing and it was standing in its default position with 218 health. I thought maybe the health would reset when hit but it only had 218 health and that was the only thing different with it. I've also saw this morning on reddit the blue being pinned by a pink ward and standing still, I don't know if this the same thing at all. The only other information I can give was it was blue side (left side of the map blue) and the mini golem with the blue buff closest to the river was dead while the other was still alive.
