Cloth bake: Certain parts of cloth deform very quickly and not consistent Sometimes, when performing a cloth bake, certain parts of the cloth "collapse" inward very quickly before the other parts have deformed. The screenshot shows what happens.



The top portion of the cloth has "collapsed" very quickly.
The preset used for this was "Denim".
Is there a certain cloth bake parameter(s) that could be tweaked to prevent this?
I am using the latest version of Blender.

Result 2: Chaning self-collision parameters. No change:



Result 3: Greatly increasing the mass. The results are now much better.
(The results seem to be the opposite of what I would expect. I would expect the issue above to happen if the mass was too high. However, the opposite effect seems to happen).
This was caused by numerous triangles which were not connected to each other on the head area of mesh. There were also duplicate vertices in the problematic area.
