"What happens when someone puts a Pokémon in a gym quicker than you"

#PokemonGO: Just a quick piece of info I discovered today that I've never seen or heard mentioned before. If it's common knowledge, please don't hate me.While I was scrolling my Pokémon list to put something in my team's gym I noticed this Rhydon was greyed out.Pic: http://ift.tt/2gnOX5t a sec I panicked that somehow I got banned (even though I never did anything against rules). When I clicked it there was a message (pink box like on pokestops or gyms) saying that "only one Pokémon of the same species can be placed in a specific gym" (no screenshot, sorry).When I closed the list it appeared that while I was browsing someone has put a Rhydon in the gym.Well, there you have it. It's trivial but cool it's been thought of. via /r/TheSilphRoad http://ift.tt/2iDpplN
