Failsafe activation during offboard


can you please look at my logs, and see what happens to position control in Z-axis.
At one point it started behaving like it is acting on RC , rather than offboard position control.
It seems like failsafe was activated , but this failsafe did not show in terminal where mavros shows errors. It is only shown in the csv of the log file in STAT_failsafe tab.

It seems like there is an override in setpoints in the Z axis.
