Hi,
I want to control a simulated Nao in Gazebo using [robocup3ds](https://bitbucket.org/osrf/robocup3ds) plugin. I need the ability to reset ball position and Nao position whenever I set the game play mode to `Before-Kickoff`. My code already works with [rcssserver3d](http://robocup-sim.gitlab.io/SimSpark/downloads.html) and [simspark](http://robocup-sim.gitlab.io/SimSpark/downloads.html). Now I need to adapt my code to robocup3ds plugin. But in robocup3ds, setting play mode to `Before-Kickoff` just resets the ball position. Nao position is sometimes reset as expected, but sometimes it is not. For example suppose Nao initial position is (0, 0, 0). Assume Nao is at position (-2, 3, 0) and fallen on the ground. Now setting play mode to `Before-Kickoff` resets Nao position to a point near its last position (e.g. (-2.1, 3.2, 0)). But the desired behavior is to reset Nao to its initial position which is (0, 0, 0).
I have spent several days to figure out what's wrong. But I failed to do so. Does anyone know what might cause such a behavior?
Thanks in advance.
