Still have the original version installed and...no bath towels in sight.
I think someone already mentioned that the bulk of the story is also in the bath scenes and SP chose between cutting all of them(butchering the story somewhat) or keep them intact(adding the towels for casual steam buyers), choosing the latter seems better storywise. I dont know how much additional work/cost or how much of an inconvinience it is to create 2 variations, a towel and non-towel, but I guess they cant be bothered and just created the toweled version and use it for both fakku and steam releases instead. R18 patch is for addition of h-scenes only and nothing more I guess.
Anyway, just gauging reactions here before I ccommit and buy.
