Nefarious ran into a nasty little bug. We were seeing some bizarre behavior of flights on a route forming a conga line instead of maintaining the desired offsets from the route origin.
After a bit of head scratching and cussing we narrowed down the pattern.
In this demo mission we have multiple flights on a common route and each has an offset forming a large bomber group. It is air-spawned.
There are a series of waypoints. Here is a happy path where everything is in a straight line. You click "run" and you see a series of parrallel lines denoting each flights path along their offset from the common route. This is how it should look. The offsets are maintained between waypoints.
What we found is if there was any turn or bend between wp0 and wp1, then something weird happened. It's like the offsets are forgotten during the turn and the formation fall into a conga line until they get past that. This is an unhappy path.
Other waypoints don't seem to have this problem. It seems limited between wp0-wp1.
Demo mission is attached.
[edit] What we are doing now for a temporary work around is starting our route with two short wp segments that can be kept in line. After that, everything works normally.
