I'm not sure if the problem is with KKPE or BetterPenetration.
While using BetterPenetration 4.5.2
I cannot specify the direction of penis when I move f_dan_entry in KKPE.
Same situation, and seems dan_entry's position is not right.
Is the KKS studio version not ready yet?
I can not found the dll for studio in KKS's release package, but the source file is there...
