Short description of error

Hello, I'm having some issues with cloth sim and shape keys, basicaly what I've seen is showed in video down below

Exact steps for others to reproduce the error

When I creating a mesh for a curtain with shapekeys it is sometimes becoming broken (Like in video down below)

1 - create a plane
2 - subdiv
3 - create vertex group and assing needed verts to it
4 - make 2 shapekeys
5 - make 2nd key the way curtains work
6 - make transition from 1st to 2nd
7 - create sim (clicking on "cloth" button)
8 - pin group = group from 3rd
8 - watch the world burning

This is process which I'm using in order to create curtains and sometimes this crayziness happens

I've made a quick setup by myself and I don't actually find any issue.
I am not sure how to comment about this report. I feel this is more looking for support than reporting a bug.

Your cloth has a couple of duplicated loops which prevent the sim to work the way it should.

Easiest is to enter editmode on Plane and do Mesh > Cleanup > Merge By Distance

Then the Physics Properties > Cloth > Shape > Dynamic Mesh is turned ON, turn it OFF (in this scenario it harms more then it help)

There doesnt seem to be a bug here indeed, will close (but of course feel free to comment again if issues persist)
