I'm now messing around with a minor error in one mission, but it affects the gameplay-feeling in a way so that I want to change it in every case. I'm pretty sure that this is not a problem with the goals or the sexpression, I tested that.
Here is a shot from the mission-area, so I can explain it better. I also placed the wellington-carrier so, like it is in the game when this problem occurs:

As you can see here, I have the carrier waiting in the center, while the ralatha-destroyer is simply ordered to follow the waypoint-path "ralatha-way" with "waypoints once". Also I wrote down the Y-Value, so you can see that he should get on a deeper level than the carrier (this way he will fire it's upper guns).
Now every time this little ***** arrives at Waypoint3, he decides that proceeding further could cause a collission, so he start rotating at fully 360 degree over his own center-axis
on the same spot, then turns to right (about 1000 meter, even if there are no waypoints) and finally then he starts moving to waypoint 4 after another turn around.

Why the hell is this happening ? Ingame there is nearly
2000 klicks space between his strange rotation-point and the parked wellington carrier, and this should be more than enough for him to simply face waypoint 4 and move towards it, or not ?
Has anyone of you coders a idea if that can be changed or if this is a
bug ? (Dynamic goals for the ralatha has been turned off btw).
This is really driving me nuts, so thanks for any help
