Here is the 0.19.1 Beta 1 release of Gone Bad Party:
https://forum.eekllc.com/viewtopic.php?p=1288#p1288
It is a first release compatible with the 0.19.1 version of the game.
Currently, 0.19.1 is only available for Patron alpha tester backers but hopefully will be available on Steam in a couple of weeks.
Main changes
Updated story to match 0.19.1 version of the game. This will make Gone Bad Party a bit easier due to change done in Original Story to have the option to tell girls to hang at specific places in the house. With that said, all around, it should be a positive change. You do need to get some friendship points with girls to be able to use this option.
Updated "the power" of the spoon. It is triggered differently, but should now affect all girls.
There are also some clothing swapping additions:
Added ability for Katherine to switch to alternate panties. Related to this, the scenario, when she can hang in the hot tub, does not require maximum affinity with her anymore.
During the dance party, if Derek is invited to join, added an option for Derek to switch different outfit.
Important notice
The custom story version of Gone Bad Party has new sexy cutscenes disabled, in places they were used in Original Story.
This is because as of 0.19.1 these cutscenes are broken when run from custom stories (they will start, but some events in them will not function correctly). On the other hand, the mod version of Gone Bad Party will have them working, exactly as is in Original Story.
And just to avoid confusion, all Gone Bad Party specific content still uses classing sex scenes, and not new sexy cutscenes, regardless of the version used. The main reason for this is that so much of Gone Bad Party mechanics depend on interactivity, which is not available with sexy cutscenes. This may be slightly revised in the future. For example, I may consider adding an option to trigger sexy cutscenes in some situations, but that is all in the future.
