if you have a lot of mods it is harder to find but open this folder "On Windows, it can be found by default at C:\Program Files (x86)\Steam or C:\Program Files\Steam" it shoudl be full of mod id numbers use explorer to search for preview png then right click on the one for the mod you want to edit (in this case slave bikini) fianly look in that folder for a .xml file(there may be 2 in witch case boath need to be edited) open the .xml file in notepad search for "<workSpeedStat>TailoringSpeed</workSpeedStat>" delete the line save the file and that should fix(i've been busy sorry will will fix when i get the chance)
