When your last pokemon faints due to recoil -

[Karmagick]

Requirements for the bug to happen:

- Have only one Pokemon able to battle

- Win the battle

- But faint yourself to recoil damage

 

What happens:

Your Pokemon are instantly healed and you get to stay where you are, however after taking a few steps you get teleported to the Pokemon center.

(I've only tested this while surfing, which resulted in me surfing inside the Pokemon center for a single step.)

 

Now this might seem to be a minor bug but I can easily see it being abusable.
