You could try with increasing the cloth distance parameter. It has been found that the value of 100 is maybe not enough. Try with 101 or such. The new code is no longer as precise as before on tight fits. I think I'll add both computation options in the next version, so one can choose. Or it could be that some morph targets have not been automatically selected. I have a report of local morph targets not being automatically selected. I have to look into.
