Hello everyone! ^^
Sorry for the disappointing news, but I'll have to push tonight's github/Patreon update back by one day. :(
I've finished refactoring all of the code that's needed for multiple-partner sex to work, but there are still quite a few major bugs that need to be fixed. I need another day to get them all sorted out, so I'll have to release the github/Patreon update tomorrow (I'll try and get it released a few hours earlier than the usual time).
Update will be: Saturday ~23:00 GMT Very soon (before 00:30 GMT)! (Just a couple of bugs... x_x)
I've updated the github, and am currently working on packaging up the Patreon preview version. Please be aware that I've updated to Java 9.0.1, so if you're building from the github, you may need to update your Java!
