"Biome shift after the event?"

#PokemonGO: Our biomes have shifted in Ann Arbor!Our Drowzee pocket downtown, as well as nearby Detroit, is now completely missing Drowzees. There are a lot more Spearows and others. We're still seeing the Jynx spawns in the Drowzee zone (she was common in the old blend), which leads me to believe they've replaced Drowzees with Spearows but kept the rest of the spawns the same.Our normal Pidgey/Rattata/Weedle biome seems very different, too. 57 tracked spawns, and I haven't seen any of them (the add up to 60% usually!) Instead, the new big three seem to be Eevee (28%, vs the old 5%!), Venonat, and Spearow. I've only seen the evolved forms of Pidgey/Rattata/Weedle!Our water biome seems to be roughly the same, as well as our Clefairy/Nidoran/Eevee biome.Very early data, but there's obviously been a massive shift.Edit 1: Whoa, weird. I'm seeing Pidgey/Rattata/Weedle on my sightings, but they're not corresponding to reality?? Maybe they're doing a client-side remap and forgot to update the sightings?Edit 2: Up to 100 spawns tracked, still not a single Pidgey/Rattata/Weedle where there were 60% before. Eevee/Venonat/Spearow have taken over as 55% of the spawns. Cumulatively they were 14% before. via /r/TheSilphRoad http://ift.tt/2f2np0o
