OK, so it has happened to me once again - I have been zapped with my shield on, so I decided to file a bug ticket for your consideration.
According to my observations, it happens only when someone jumps over (random skip in the line) during the encounter

In the pic. 2c orange didn’t skip over me, I must have jumped instead.
