If you are using the walkthrough mod then friend is still how its worded that mod has not been updated in a long time. there is one other making a new mod now to try and help out where the other mod is now far behind.
sancho1969 is working on a new mod but its not ready for posting hopefully it will be at some point.
I am for example going through most of OscarSix's mod and adding in all the corrections from captains edited files to his mod then hopefully I can figure out what more to add to make it compatible with the v5.5 + 6.1 changes the last version of that mod was in v5.3 but I am no expert in mods to really figure out what would be the best choices. and hopefully the edits I am doing should make the mod actually work with the incest patch in the current version it is not because what the patch is looking for and what it is seeing are not the same so no corrections are made from the patch. Also adding in the achievements that did not exist prior. I dont know if it was supposed to get corrected or not by the incest patch but there is a part where it says "My stepsister loves my cock" on day 3 I know this is part of the research but when the patch is active she is not a stepsister. but that is up to the person who edits the patch to make that change.
Hopefully someone is able to make a walkthrough to show best choices for the paths chosen.
