PokemonGO in hard mode? No, a bug... and still running...

Catching a Celebi was hard??? It didn´t get any closer to this bug...
It started without any forcing method, just happened. I tryed to catch a larvitar and the game showed this bug...
I spent lots of balls maybe 30 and for my luck I had a lot. Later any other pokemon I tried to catch this bug is still running...
Maybe it will last till I restart.
But do I want it??? Would you want it???? hehehehe
