Found a Bug In Catching Pokemon

If you have multiple tabs open in Lake Valor with Pokémon that have appeared you can catch them without using any balls.

1. Find a Pokémon, don't click catch yet.
2. Open a new tab in the site until a second Pokémon appears there, don't click catch yet.
3. Click catch on the one you want.
4. Keep using balls until caught. (or failed to catch)
5. Click catch on the Pokémon in the other tab, your ball count will be reset to where it was.

I found it by accident when browsing in multiple tabs. I know it works with pokeballs, not sure about others.

Basically, when you see a Pokémon you want, open tabs until something else appears, catch the one you want, and click catch on the second to reset your balls.
