62.000 prestige gym? is this a bug?

i believe its simply max prestige through training, then add 10th pokemon.

Seems what happened is someone trained it from level 4 to level 10 (50,000 prestige) opening up 6 available spots. Then 6 people dropped in defenders, each adding 2,000 to the total resulting in 62,000. My team will do this a lot, 4 of us drop in and we all train/boost it up so allies can drop in.

The extra prestige points over 50,000 don't actually have an effect however (just cosmetic, kind of a bug). What I mean by that is no matter what the prestige amount says for a level 10 gym, it is functionally still 50,000. So if an enemy attacked and beat just the first defender it would knock it down from 62,000 to 49,000 (50k - 1k for the mon beat).

If someone bubbled the gym to 50,000. Each pokemon added will still show a 2000 prestige addition past 50,000. However the 1st battle will remove all excess prestige.

Instinct, not mystic.
