void ZoneDatabase::AssignGrid(Client *client, float x, float y, uint32 grid)

if(matches == 1)

should be:

if(matches > 1)

Change first query to:

	std::string query = StringFormat("SELECT id, x, y FROM spawn2 WHERE zone = '%s' AND x = %i AND y = %i",
                                    zone->GetShortName(), x, y);

This will help you temporarily until that section of the code is cleaned up.
