I have had a repeating (but occasional)  problem with dynamic hair that I make where some hairs fly off in a sort of ascending scatter of individual hairs (or hair guides) from one of several hair groups only. The first time this happened I located the group and deleted it - then rebuilt the group - and no fly off. It has just happened again with a new hair composition and seems to be from the same place - right rear on the wig base.

Anyone seen this or have suggestions? The weird thing is it seems to be from the same area in a dynamic hair construct.
