Soft body behavior is incorrect when CTRL + F12 animation is rendered.
Open, Confirmed, MediumPublic

Description

Operating system: Windows10 64Bit
Graphics card: Nvidia GTX1080

Broken: 2.81 2.82 ALL

The animation in 3D view is correct,
I cannot get the same image as the view that performs CTRL + F12 rendering.

If you execute CTRL + F12 rendering after displaying the intermediate frame in the 3D view timeline, the image will be even more strange.

The correct image was obtained with only one rendering of F12.

I confirmed that the correct image can be obtained when loop rendering is set in python and the index of point_chach is set.

Attach the file used for verification.

Since it was a Japanese file, I will attach an English version just in case.

I can confirm. The bouncy ball should go between the red lines, and then through the red circle. It does so in a viewport render, but not in a render render.

I can also reproduce the issue in just the viewport. Go to frame 101, press Space to play, press Esc to stop playback around frame 120. This goes back to frame 101, where the curve has an offset from the bone it's attached to. I gave the curve some thickness to make it more visible:
