**System Information** Operating system: Windows-10-10.0.19041-SP0 64 Bits Graphics card: NVIDIA GeForce GTX 1080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 511.09 **Blender Version** Broken: version: 3.0.1, branch: master, commit date: 2022-01-25 17:19, hash: `rBdc2d18018171` Worked: (newest version of Blender that worked as expected) **Short description of error** Whenever I modify the 'basis' shape key, select the vertices I have changed and try the "blend from shape" operator it does nothing. Any other shape key, when applied, makes the modified vertices go to the original position. The "propagate to shapes" operator is flawless, always works, but it has the inconvenience of destroying the other shape keys on the applied area, and thus could only be applied on areas untouched by any shape key. **Exact steps for others to reproduce the error** - I change the vertices positions of a mesh in the 'basis' shape key slot (the mesh has other shape keys already made). - I select all the vertices which have been position transformed and select 'vertex >blend from shape'. I doesnt't work. OBS: I suspect there is something to do with areas that already have other shape keys applied, for areas without intervention the 'blend from shape' works similarly to 'propagate to shapes'.

One othe robservation is that almost all my shape keys have drivers applied to them.
