Get the error to occur again, then I may be able to help you.
lastexception.com is managed by Turbodriver. Turbodriver is a slanderer against me and also the one that put malicious code within Wicked Whims, I 100% do not trust anything that come from that site and neither should you. (Especially when it mentions any of my mods, because it lies) ColonolNutty is not a mod and I do not manage only a single mod. I manage quite a few.
The only time DD does anything with sliders is with the CSF Breast Sliders and only when DD Milk Farm is installed.
If your Sim is mobile milking, no milking station is needed.
I am currently banned from LL, so I cannot access the website to retrieve the link, sorry.
DD does not know nor currently care about Genders, DD only currently cares about sexual organs. I do have some ideas of how to add something like what you are suggesting, but it will be for a combination of Gender + Sexual Organs that will determine orientation.
