I've linked to a short comparison video that shows the same mission with spline waypoints on the left and normal waypoints on the right. As far as I can tell, it happens with and without a ROI. Sometimes, it's veers off way further than in the comparison video. It's like it wants to point to 180 degrees or 0 degrees, then corrects itself.\r\nhttp://youtu.be/PTwXBoFAxxY"},"comment":{"url":"https://api.github.com/repos/diydrones/ardupilot/issues/comments/122143786","html_url":"https://github.com/diydrones/ardupilot/issues/1638#issuecomment-122143786","issue_url":"https://api.github.com/repos/diydrones/ardupilot/issues/1638","id":122143786,"user":{"login":"rmackay9","id":1498098,"avatar_url":"https://avatars.githubusercontent.com/u/1498098?v=3","gravatar_id":"","url":"https://api.github.com/users/rmackay9","html_url":"https://github.com/rmackay9","followers_url":"https://api.github.com/users/rmackay9/followers","following_url":"https://api.github.com/users/rmackay9/following{/other_user}","gists_url":"https://api.github.com/users/rmackay9/gists{/gist_id}","starred_url":"https://api.github.com/users/rmackay9/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rmackay9/subscriptions","organizations_url":"https://api.github.com/users/rmackay9/orgs","repos_url":"https://api.github.com/users/rmackay9/repos","events_url":"https://api.github.com/users/rmackay9/events{/privacy}","received_events_url":"https://api.github.com/users/rmackay9/received_events","type":"User","site_admin":false},"created_at":"2015-07-17T01:29:08Z","updated_at":"2015-07-17T01:29:08Z","body":"@mmaunder, Sorry for the delay in looking at this.  Were you using DroidPlanner or Tower maybe to create the mission?  My guess is that the ground station was trying to be helpful and created all those extra ROI commands.  There was an issue in AC3.1.5 (I think) where ROI would not persist across waypoints so maybe the Tower/DroidPlanner guys tried to create a workaround that went wrong in this case?"}}
