Broken: version: 2.90.0 Beta, branch: master, commit date: 2020-08-17 19:04, hash: rBe157573fab2a
Worked: (until blender 2.80)

Short description of error
[OMG...I am excited to report this is my first time reporting....you have no idea how shocked I am when I discovered this problem...Its very simple to spot but no one reported.
I have tested this bug on v2.79,v2.80, and on more recent versions of v2.83.4 and v2.90.0Beta ...I think the bug started on v2.80 and no one discovered it....rigid body physics animation miss behaves and even crashes if you change between scenes with a (full copy) scene]

Exact steps for others to reproduce the error
[step1. make the default cube a rigid body,
step2. make a new scene with (full copy),
step3. play the animation on the second scene and stop it after a few frames,
step4. change the scene to the first scene and play the animation for a few frames,
repeat the last to steps until it crashes]
[Based on the default startup]

Thanks!
I am very proud of you guys!
