I have never seen or heard of that specific bug...but I would report it to Niantic and encourage all who took part to do the same thing.
They will probably compensate you with a raid pass or 2, but the important part is that they will hear about a serious issue that has the potential to affect a large number of people simultaneously. Hopefully this would be taken seriously.
...and if my eyes are not real, then what is it I am seeing in the mirror?
