"Spawn point REMOVED at silver tier unlock"

#PokemonGO: At home I have three regular spawn points, at :27, :46 and :50. These have always been here and never changed.When bronze tier was unlocked, I gained a further spawn point at :49 (this is one which appears regularly during events).When we hit silver tier today, I gained two more - one at :20 (which I have not seen before - even in previous events), and one at :33 (which has shown up before during the last couple of events). HOWEVER, since unlocking the silver tier, my trusty old :46 spawn point has vanished (have checked the last two hours). Has anyone else seen this? I'm especially interested as it's one which is normally unaffected by events.Edit: This isn't meant to be a complaint - my number of spawns have increased overall, but if others have seen this happen too and have not gained new spawn points in their place, then they would see an overall decrease in spawn points. via /r/TheSilphRoad http://ift.tt/2A14Wy8
