In the new open beta there seems to be a gun pipper lead calculation bug. This only happens the first time a mission is run in DCS. After that first mission ends when loading the mission again the bug is not there.
Steps to reproduce:
1. Start DCS and load the track attached. The gun pipper lead is off so when placing it in the target the bullets will go in front not hitting it. In order to be able to hit it I had to place the pipper behind the target. (in the track you can see me trying to place it in front first, only when placing it behind it I achieved a hit).
2. In the same DCS session. Load the track attached again. The gun pipper will now show the right lead calculation. (it could also just be a bug in the Y axis of the pipper placement instead of a lead bug).
I am also attaching a couple of screenshots, both taken at the same time from the attached track file. The first one shows how the pipper is displayed the first time the mission is run. The second one shows how it is displayed the second time the mission is run.
