System Information
Operating system: Windows 10
Graphics card: GTX 1080

Blender Version
Broken: 2.90.1
Worked: Unknown

Short description of error
Vertex from converting edge to geometry end up missing when the mode is changed.

Exact steps for others to reproduce the error
With the 3D cursor align mesh edge vertex to the hand bone joints.
Transform the edges into geometry to make fingers.
Made the fingers as part of the palm mesh (Ctrl+J).
Then I attached the fingers by joining vertex (M).
It came out as intended.
Added UV seams.
Changed to sculpt mode.
The fingers became a color different than the shading, masked on its own?
Change to edit mode.
Vertex vanishes from the fingers.
Can't displace the fingers in edit mode as scale and transform or rotate require vertex to function.
To fix the missing vertex: delete 1 face at a time then select 2 edges and (F) to fill 1 at a time.
All the vertex are back as intended.
Change to sculpt mode.
Change to edit mode. Vertex from the fingers has vanished once more.
Can't edit anything in this file or else the hand loses its vertex.
I wish there was a fix for this but I didn't find any other way than keeping the hand in another file till everything is edited for the rest of the model then reattach the hand last.

Can you upload example file before step which caused vertices to dissapear?

I think it would be more helpful to understand what happened and why.

Here is the previous save I made, I already made 2 new fingers the index and middle. Notice the modifier I was using: Subdivision, when I delete the Subdivision modifier or apply it notice in Sculpt mode the new fingers are a different color than the rest of the hand. Previous save from that I didn't change the hand yet and appears normal.

Somehow the vertices are hidden yet the connected geometry is still being drawn in edit mode. You can unhide the verts by doing the Mesh -> Show/Hide -> Reveal Hidden, then you'd be able to transform them. Be interesting to know though which tool or combination of tools put the mesh in such state.

There is still a bug
In edit mode > Show/Hide > Reveal
That will shows the vertex in edit mode but when you go into sculpt mode the geometry is still unseen.

There is still a bug
Normally, hiding using (H) when only vertex is selected also hides all faces and edges involved with the vertex.

Yes, there is still an issue, I don't dispute that, only advising you that you can salvage the model without having to rebuild it. You can unhide the geometry in sculpt mode as well. After which you can work with the model normally. The question is, how/which interaction between sculpt and/or edit modes put the mesh in such incorrect state to begin with. I tried reproducing this on a clean file using the steps you outlined in the report, with no luck.

Pretty sure this is already resolved in 2.91, see #80771 (Mode switching hides vertices in Edit mode (Weight paint / Sculpt mode --> Edit mode)) / cacd57b67a

Please try a fresh build from https://builder.blender.org/download/

Will merge into #80771, feel free to comment again though if you manage to reproduce these issues in 2.91 onwards as well, thx!
