so... Does anybody has a fix or workaround on this? Aside from relaunching the app or rebooting the phone.
Is there any way to tell if a gym is bugged so we don't have to click it?
Edit 1:
Nevermind, i have successfully reproduced the bug just now. It's a combination of (1) game design, (2) niantic's unpatched minor issue, and (3) an exploit easily fixed by a banwave. And it looks like it's not gonna go away until the next patch.
It has
nothing to do with the type of phone you have, which team the gym belongs, who is the gym leader, the pokemons inside, nor the type of account you have. It's different from the egg bug and the grimer/muk bug. This bug exploits the little known and "overlooked" feature/design of the game.
Let's see how fast niantic can figure out what needs to be "changed" on the game. By the looks of it, this bug isn't gonna go away soon, and more occurrence is expected because more people are unconsciously "using" the cause of this bug.
To those who knows this and is keeping quiet, please don't be greedy... Let others enjoy the game -_-
