Maybe bug? Out of sync last_angles (SDK version 1.6.10) about xarm-python-sdk

[vimior]

Thank you, _sync will synchronize the reported position to the recorded value sent last time, but if the last motion command is non-blocking, then you want to perform relative motion at this time (or you did not specify all joint values (or X/y/ z/roll/pitch/yaw value)) will be problematic.
The value of last_used_angles will be updated synchronously when the robot arm is in a normal state when it is reported for the first time

This occurred after several commands in normal state. I think it was the first joint command though. What should I do to make sure values are correct before issuing the joint command? Doing a relative command of all zeros forces resync?
