Problem with obsticle avoidens in flight mission.

[Zodiak06]

when i fly a mission and for some reson there is an obsticle in the path. my mavic just stops and paus the mission. if i fly around it manualy and try to restart mission from pauspoint mavic just turns around, see the obsticle and paus again. i have my setting on go around, not stop and still it only stops avery time. background, my worksite have many erected cranes that move around so it is difficult to make a mission to avoid them all. any thouts?
