I was wondering if anyone saw something similar to this. I am using a tracker that lets you know how long the pokemon will be spawned for. Most stuff lasts between 5 and 15 minutes, but I am seeing one or two that are set to despawn in over 500 hours. I haven't been able to verify this yet, but I will be checking it out this morning for an abra I saw in south philly. They appear to be only in nests or highly active areas. The other one is a magikarp on the schkuykill river (I thought this area was a psyduck nest, but they only seem to appear at certain times of day. Magikarps are there regularly though, not counting the 500 hour one). Has anyone else seen this sort of thing and been able to confirm it?
