Did anything change in multiplayer/tracks

[Gunfreak]

I did a small missions this week.

F4 takes off from Marianas and attack an airfield.

I ran through the track twice and it worked fine. 

 

However after yesterday's patch.

When I try and run the track one of two things happen.

1. In the track saved on my dedicated server track the F4 just stands on the runway and nothing happens (in the mission I had it on take off from runway, but since I ran the mission from a dedicated server in the mission i started in parking hot) 

2. The track saved in my dcs multiplayer track folder the F4 starts on the runway. Then drives straight over the grass and parks in one of the parking spaces.

 

So in both cases the F4 starts on the runway (as per the mission set up)  but nothing like the the mission i flew or the tracks from before the patch.

 

I wouldn't call a bug. I'm just curious if something has been done in the patch to explain the behaviour.

Tracks are notoriously fragile across versions...

Tracks are only valid on the versions they were recorded on. Sometimes there are exceptions.

What the other guys said.  Tracks (which were not designed for exact replays but are currently the only way to get any in game replay) do not do well when replayed in a different version because of the way they work.  They literally replay the inputs made in game (at something less than 1:1 fidelity or file size would be crazy huge) so when things are changed in a version change you get very different results.
