I put up a gym in Foretree Village (I think that what it's called) and I can't find it. It says on the right that there is one Pokemon in a gym. The team is mystic and the Pokemon that I put in it is a lvl 15 Meowth. I will give 10 revives to the person who finds it. I would give a Pokemon but I'm not that high a level yet.
This might be the glitch that everyone is having where their pokemon gets defeated but their poke says its still in a gym
Each server has its own set of gyms claimed by a different team so Check all the servers and try to stick with the same one for lower or no confusion If that dosen't work then you are lucky free tokens
