System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GT 635M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 388.71

Blender Version
Broken: version: 2.90 (sub 0), branch: master, commit date: 2020-05-01 21:55, hash: 83304e4c22
Worked: (newest version of Blender that worked as expected)

Short description of error
Changes to Level 1 (and higher) cannot be propagated down to Level 0 using the "Apply Base" button after Shapekeys have been added.

Exact steps for others to reproduce the error

SubDivide the default cube using Ctrl+3 and apply
Add a MultiRes modifier and press "Subdivide"
Do some sculpting at Level 1
Press "Apply Base" - going back to "Sculpt" Level 0 shows the sculpting has been applied.

Scenario A:
5. Add a shape key ("Basis")
6. Do some more sculpting at Level 1
7. Press "Apply Base" - going back to "Sculpt" Level 0 shows nothing happen

Scenario B:
5. Add a shape key ("Basis")
6. Do some more sculpting at Level 1
7. Press "Apply Base" - going back to "Sculpt" Level 0 shows nothing happen
8. Add a second shape key ("Key1")
9. Scrubbing the "Value" of Key1 between 0 and 1 shows the sculpting from Level 1 being applied to the Level 0 mesh. (Bizarre! "Apply Base" was pressed before Key1 even existed!)

Scenario C:
5. Add a shape key ("Basis")
6. Add a second shape key ("Key1")
7. Do some more sculpting at Level 1
8. Press "Apply Base" - going back to "Sculpt" Level 0 shows nothing happen
9. Add a third shape key ("Key2")
10. Go to Sculpt Level 0.
11. Scrubbing the "Value" of Key2 between 0 and 1 shows the sculpting from Level 1 being applied to the Level 0 mesh (which is what was originally wanted)
12. Go to Sculpt Level 1.
13. Scrubbing the "Value" of Key2 between 0 and 1 shows the sculpting from Level 1 (Value = 0), and double the deformation (Value = 1) - bizarre, and very unexpected!

This is a known issue. See: #73317

Investigate how to support "Apply Base" for meshes with shapekeys

But I am confirming it as a Bug since it is to be solved soon.

Germano Cavalcante changed title from ~~MultiRes cannot "Apply Base" when ShapeKey have been added. Odd behaviour when additional shapekeys added.~~ to MultiRes cannot "Apply Base" when ShapeKey have been added
