Seems like this is my mistake for using float numbers in some places causing scripts to missfire. You can edit your save file with text editor and change line "mainquest":28.1 to "mainquest":29. I'll try to fix it properly next update.

Okay, thank you! Also, in that same save file, you might want to have a look at the slaves I've gathered. I put nature tattoos on all of them, and for the majority I placed it on all six parts, except the Orc (Ushaga), who has a different tattoo on her legs and ass. As it turns out, she's the only one who receives any benefit from the tattoos. Looks like its effect is broken on everyone else.
