This is how it looks before I move a pet spell: http://prntscr.com/kpjj1w

and this is the after pic: http://prntscr.com/kpjjbb

The grey boxes don't go away and overlap the quests too. When I /reload the game it's fixed again, but as soon as I move a pet spell again it bugs out.

Great addon though. 

While this issue exists within the default UI, this particular report is valid, as Bartender doesn't use the same implementation for hiding and showing the grid. The issue is that when you move around a pet icon, the grid for all other bars remain visible even after "dropping" the icon. Tuller has a fix within Dominos, but Dominos uses the default API, so that fix doesn't work with Bartender.

What *should* happen is that whenever any icon is "dropped", any empty buttons on bars without their grids enabled should be hidden.

Closing old issues. If your issue persists, please create a new issue with full details.
