"Strange behaviour in local nest."

#PokemonGO: Their is nest near my area which was originally magnemite-> ponyta -> slowpoke Now today i first thought it changed into nothing but after continuously scanning all day, i concluded it has changed into sandshrew nest although the frequency is lower than before. Now the strange thing i noticed is that for around an hour, it changed into a charmander nest..like charmanders everywhere l, i caught like 10 of them in 20 minutes. But then they just dissapeared altogether and sandshrews came back. No sign of charmanders now.Anyone noticed such behaviour?Edit: Looks like the park now has 2 nests- charmander and sandshrew..wow via /r/TheSilphRoad http://ift.tt/2dpp8jz
