System Information
Operating system: Linux-4.15.0-47-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: Mesa DRI Intel(R) UHD Graphics 620 (Kabylake GT2) Intel Open Source Technology Center 4.5 (Core Profile) Mesa 18.0.5

Blender Version
Broken: version: 2.80rc1
Worked: blender 2.79b

Short description of error
I made a rigid ball bouncing on a soft box physics simulation in 2.79, with a little trick by placing another rigid plane inside the box.
However when I bake the soft body box in 2.80 again, the soft body box does not collapse and the rigid ball just went straight through.
It should also be noted that I have also tried to create the same thing 2.80, still doesn't work. Hence I decided to created a 2.79 file and open in 2.8 to prove that my setup is correct.
b280.mkv
b279.mkv

Exact steps for others to reproduce the error

Open the Blender 2.79 file in 2.80.
Bake the soft body cache of the box.

I'm getting this error printed in the terminal (probably related to this issue):
