I have just released Version 5.2 of the Revolutions to address some odd problems with the nipples.
Firstly there seemed to be a bug that was affecting nipple texturing and colouring - unsure why this happened as it never showed up during testing. Have extensively checked the scripting and rewriting it, these issues have now been solved and everything is working perfectly.
Secondly was one of the more irritating bugs again with the nipples. On the BOM version obviously nipples are not going to work with clothes, and in pretesting I ensured you could hide the nipples, however I broke the cardinal rule and forgot to reset the scripts before release. Even on the version on my side the show / hide nipples menu was working. This has also been addressed and repaired in this update.
If you need to grab a fresh copy, head over to the Market Place and redeliver, or go in world to the main store and go to the Casper Redelivery point - even if you bought on the Market Place, you can get an update there as well.
