Is Niantic getting sloppy?

What mikeyface has said. When have Niantic ever not been sloppy!

I get weird glitches almost every day, one time after feeding berries i exited the gym, the berry followed me around and i was able to feed myself and pokestops berries! On other occasions pokemon next to me randomly shrink to minuscule sizes.

When glitches like this occur, you shouldn't ever be surprised when something messed up happens like a gym disappearing.
