Helicopters are bouncing around wildly on startup of missions

Do you have the same issue if you follow the OP’s steps to reproduce it?

Provide extra information to complete the original description of the issue:
• This seems to occur for me even when I did not transfer the helicopter to an area of different elevation. I tried restarting the game multiple times to no avail, and have lost a significant amount of reputation and credits (due to having to repair significant damage) because of this bug. It happens any time I try to load into any mission now in the Guimbal Cabri G2. I am using an absolutely “stock” install, with ZERO mods and nothing in the Community folder.

If relevant, provide additional screenshots/video:
• I would provide a video, but I don’t want to cost myself even more bad reputation and credits.
