Hi
what fix was done for that function ? This problem:

is solved ?

Hi @norim

Here’s the issue and PR related to the condition-yaw command problem. The issue only happened when WP_YAW_BEHAVIOR = 0 and a relative condition-yaw command was executed.

The slightly annoying issue of the vehicle slightly changing its heading has not bee fixed yet unfortunately.
