I think some caravan/visitors want to enter your map and the mod DontShaveYourHead got problems to create the proper hair for them.

Maybe a modconflict with an race or appearal you extra use.
You should post an error log made with hugslib or the output_log.txt from the data folder at the mod-topic so the mod author can take a closer look.
