Fixed: 0 Hair amount error
Improved: exportable hair amount

Hair exported only the view percentage, full amount gets exported now. allowing much higher counts than what could get displayed. also since the lowest count (0) is no longer divided by the view percentage it removes a "division by 0" error.
