Bug catching area "glitch"?

[Mjew]

Good evening,

While i was doing my daily bug catching area 20min I ran into a mothim.

So I threw an ultraball at him and poof i was instantly ported to olivine.

I had a little less than 10 minutes left in the area before i was supposed to be finished so that can't be an explanation.

Found it very weird therefore decided to report it, is this a known issue?

Thanks for taking the time to read/respond, all the best.
