The most satisfying thing to do with Reinhardt is to be able to steer around while charging and then pinning an enemy along the way. His charge is considered as one of the most important mechanics in Overwatch as it can completely change the outcome of a game. As of now, Overwatch has a bug where Zarya cannot be pinned by the enemy Reinhardt, but instead he charges through her like she's a spirit of some sort.
This game changing bug was discovered by Reddit user vex91 while playing as Reinhardt. Initially, he thought that it might be lag issues that caused this to happen but then it kept happening even though everything was normal. "I'm not sure if anyone else has experienced this before or if it's a known issue or not, but there may be some sort of bug where under certain conditions, Zarya is unable to be pinned by Reinhardt. I've noticed this once or twice before and kind of brushed it off as maybe lag or something, but then it kept happening so I started actually paying attention to it and recording the incidences. It has only ever happened to me while trying to pin specifically a Zarya which leads me to believe that it's not lag. Would be great if Blizzard could address this if it is indeed a bug. It's pretty frustrating when it happens," vex91 posted.
Vex91 is not the only player that has experienced this, even Zarya players felt weird when they clearly saw a Reinhardt charging towards them and they know they will be pinned but somehow he just charges through them. Another Reddit user, RoobyS stated that the bug occurs whenever Zarya uses her bubble, doesn't matter on herself or her teammates. The bug was also reported to happen not only on PC but PS4 and Xbox One as well.
I have not encounter this bug since I don't play as Reinhardt at all (I suck at him). If you have seen or have the bug happen to you while you're playing as Reinhardt or Zarya, feel free to share it with us.
