Alright, been chaining on Mirage Island for Minccino for a while now. My Minccino encounters were up to around a level 54-56 average (its default is 36-38) when I get a "Pokemon not Found. Try another area." As I attempt to find another place to find one, a Minccino pops up as I'm walking. Its level has been reset to 38.
According to a question earlier asked by me, as long as I officially encounter the Minccino, kill it, and continue searching for them, the chain will not be broken, but I would like confirmation...because I think the level resets automatically around 100 but I wasn't sure I had made it that far.
